湖南大学谭蔚泓院士团队: 聚吡咯纳米便携式水凝胶，现场手机比色法检测胆固醇 - 知乎

湖南大学谭蔚泓院士团队: 聚吡咯纳米便携式水凝胶，现场手机比色法检测胆固醇 - 知乎切换模式写文章登录/注册湖南大学谭蔚泓院士团队: 聚吡咯纳米便携式水凝胶，现场手机比色法检测胆固醇水凝胶更多原创内容欢迎关注微信公众号「水凝胶」【背景了解】胆固醇是人类必需的脂质，是激素系统的构建单元，是类固醇激素的唯一前体，并参与多种维生素的合成。在血清中，高胆固醇水平与多种疾病有关，包括冠心病，心血管疾病，高血压，心肌梗塞和癌症。但是，低胆固醇水平会导致低胆固醇血症，这可能会导致出血性中风。因此，开发一种简便，廉价且可靠的血清样品中胆固醇检测方法非常重要。迄今为止，已经提出了几种方法来检测胆固醇，例如电化学分析，基于荧光的测定，高效液相色谱法，分子印迹聚合物技术，化学发光和电产生的化学发光。这些策略中的一些显示出高灵敏度和良好的选择性。但是，它们通常需要昂贵的设备并且很费时间。比色法由于其快速和简单的操作而引起了极大的兴趣。此外，可以用肉眼观察检测结果，不需要昂贵的分析仪器。当前，基于纳米材料的人造酶，例如Fe3O4纳米颗粒，石墨烯纳米球，金纳米颗粒，MoS2纳米片，CuO纳米颗粒和金属有机框架，由于它们的活性高，价格便宜且易于制备而受到广泛关注。然而，许多金属纳米粒子聚集或呈现对固有性质的协同作用，从而导致活性降低。开发具有高催化活性和良好的长期储存稳定性的纳米酶对于解决这些缺点很重要。聚吡咯纳米颗粒（PPy NPs）是吡咯的一种有机导电聚合物，由于其高导电性，良好的热稳定性和出色的生物相容性，在生物传感和生化应用中引起了广泛的关注。PPy NPs可以吸收近红外光并将能量转化为热量，因此可以用作治疗癌症的有效光热疗法。此外，PPy NPs通过电荷转移机制可以用作有机荧光染料的强力猝灭剂。【科研摘要】湖南大学谭蔚泓院士团队报告了一种通过耦合聚吡咯纳米颗粒（PPy NPs）和胆固醇氧化酶（ChOx）的过氧化物酶样活性来进行胆固醇检测的简便方法。ChOx可以催化胆固醇氧化生成H2O2。随后，PPy NP作为一种纳米酶，诱导H2O2与3,3'，5,5'-四甲基联苯胺（TMB）之间的反应（示意图1A）。在最佳条件下，TMB在652 nm处的吸光度与胆固醇成正比，浓度为10至800μM。胆固醇的线性范围为10–100μM，检出限为3.5μM。该报道的方法成功地用于检测人血清中的胆固醇。回收率范围为96-106.9％。此外，作者使用提出的系统设计了一种简便的便携式测定试剂盒（无需仪器），实现了人血清中胆固醇的现场半定量和视觉检测（示意图1B）。从便携式测定试剂盒中检测到的胆固醇含量与基于溶液的测定获得的胆固醇含量非常匹配，因此在临床诊断和健康管理方面具有巨大潜力。示意图1.（A）使用PPy NPs作为过氧化物酶模拟物进行胆固醇检测和（B）通过便携式测定试剂盒对血清样品中的胆固醇进行检测的示意图。PPy NP的制备与表征PPy NP的形成机理如图S1所示。简而言之，吡咯单体在FeCl3的氧化溶液的存在下聚合。PPy NPs是通过Py的自由基阳离子形成而合成的，并使用PVP作为封端剂。透射电子显微镜（TEM）结果表明，所得PPy NPs（图1A）是离散的，无定形的（插图1A，插图），均匀（平均直径：40 nm）和分散良好（流体动力学直径：约50 nm）。傅立叶变换红外（FTIR）光谱（图1B）显示了PPy NP的峰，即3410 cm-1（NH拉伸振动），1650 cm-1（NH键变形），1561 cm-1 （在吡咯环中拉伸振动C═C键），1465 cm-1（在环中C–N拉伸振动），1298 cm-1（CH键的面内振动），1214 cm-1（N–吡咯环的H弯曲拉伸模式），1048 cm-1（C–H和N–H键的面内拉伸振动）和928 cm-1（C–C键的拉伸振动）。PPy NP的紫外可见光谱在400-900 nm的波长范围内显示出较宽的吸收带（图1C），这表明掺杂的PPy处于双极化金属态。图1.（A）TEM图像，高分辨率TEM图像（插图）和选定区域的电子衍射（插图）。（B）FTIR光谱。（C）PPy NP的紫外可见吸收光谱。（D）不同系统的紫外可见吸收光谱：（红线）TMB + H2O2 + PPy NPs，（黑线）TMB + H2O2，（蓝线）TMB + PPy NPs。插图显示了显示颜色变化的数码照片。PPy NPs的过氧化物酶样活性通过在H2O2存在下催化TMB来检测PPy NPs的过氧化物酶样活性。如图1D所示，与TMB + H2O2（黑线）或TMB + PPy NP（蓝线）相比，TMB + H2O2 + PPy NPs（红线）的吸光度得到了提高。这些结果表明PPy NPs固有的过氧化物酶样活性。最佳的催化条件是通过改变pH，温度和反应时间来进行的。由于具有最高的催化活性，因此选择的pH为3.0，温度为45°C。TMB + H2O2 + PPy NPs系统的吸光度随时间增加，直到在30分钟内达到平衡。因此，选择30分钟作为最佳反应时间。还评估了以TMB和H2O2为底物的PPy NPs的催化动力学机理。反应速率与底物（TMB和H2O2）浓度之间的关系可以使用Michaelis–Menten方程（等式1）进行模拟1/V=(Km + [S])/(Vmax X [S])（1）在这里，V和Vmax代表初始和最大反应速度，Km代表米氏常数，[S]是底物浓度。根据该方程式，可以计算Km和Vmax并评估过氧化物的模拟酶活性。如图2A，B所示，V随着TMB或H2O2浓度的增加而增加，并且氧化反应遵循典型的Michaelis-Menten行为。PPy NPs对TMB（0.293 mM）和H2O2（0.184 mM）的计算Km值低于文献中报道的纳米酶的Km值。低Km揭示了酶对底物的高亲和力。此外，TMB和H2O2的Vmax值与纳米酶相当，这进一步证实了聚合物PPy NPs具有很高的过氧化物模拟酶活性。图2. PPy NPs对TMB（A）和H2O2（B）的稳态动力学测定。该值是使用NaAc-HAc缓冲液（0.2 M，pH 3.0）中的PPy NP（20μgmL-1）测量的。胆固醇检测在检测系统中，胆固醇的吸收强度保持不变，并且H2O2介导的TMB氧化几乎不受胆固醇影响。通过优化ChOx催化胆固醇氧化的浓度和反应时间（图S8），可以通过将ChOx与PPy NP催化氧化偶联来实现胆固醇检测。图3A显示了在不同胆固醇浓度下的相对吸光度。吸收强度随胆固醇浓度（10–800μM）的增加而增加。当胆固醇浓度介于10和100μM之间时，在652 nm处的吸光度呈线性，相关方程A = 0.003C（胆固醇）+ 0.33（R2 = 0.9984）（图3B）。检测限（LOD）估计为3.5μM（3σ/ k）。所建议的方法在10μM和100μM胆固醇下进行五次重复测定的相对标准偏差分别为1.53％和3.02％，证明了良好的重现性。图3.（A）不同浓度胆固醇的紫外可见吸收光谱。（B）吸光度峰值与胆固醇浓度的关系图。插图：图的放大倍数在10–100μM范围内。方法的选择性此外，研究了血液中具有不同干扰的胆固醇的浓度，例如尿酸，尿素，半胱氨酸，甘氨酸，MgCl2，谷氨酸，葡萄糖，抗坏血酸和多巴胺。如图4所示，与尿酸，尿素，半胱氨酸，甘氨酸，MgCl2，谷氨酸，葡萄糖，抗坏血酸和多巴胺的干扰相比，存在胆固醇（0.5 mM）时在652 nm处的吸光度显着增加（2 毫米）。胆固醇与这些干扰物质之间吸光度提高的差异具有统计学意义（p<0.01），表明本方法对胆固醇的检测具有良好的选择性。< span="">图4.该方法对胆固醇（500μM）和干扰物质（2 mM）的特异性，包括尿酸，尿素，半胱氨酸，甘氨酸，MgCl2，谷氨酸，葡萄糖，抗坏血酸和多巴胺。人血清中胆固醇的检测为了证明研究的分析可靠性，将人血清样品用于测试。作者应用标准添加方法估算了五种不同血清样品中的胆固醇水平。之后，将一系列胆固醇浓度（0、2、20和50μM）以等体积掺入血清样品中，并测量胆固醇。如表S2所示，结果表明加标样品的回收率良好，为96％至106.9％。血清样品1和血清样品2中的胆固醇浓度分别为4.21和3.50 mM。同时，使用建议的方法检测到的胆固醇含量与使用ELISA试剂盒检测到的胆固醇含量一致，这表明在实际应用中它可能是可行的（表S2）。使用相同的方法，其他三个血清样品中的胆固醇浓度分别为3.08、5.30和4.86 mM。表2.人血清中的总胆固醇检测此外，通过使用琼脂糖水凝胶构建了一种简单的便携式测定试剂盒，以开发一种简便的方法来进行血清中胆固醇的现场检测（方案1B）。首先，确认便携式测定试剂盒对干扰物质表现出良好的选择性（图S9）。为了进一步研究便携式测定试剂盒在实际样品检测中的适用性，进行了以下实验。在琼脂糖水凝胶形成过程中，将PPy NP，TMB，ChE和ChOx预加载到琼脂糖水凝胶中，然后转移到管帽中。将不同浓度（0.1–0.7 mM）的胆固醇移入试管中，并与琼脂糖水凝胶一起孵育。如图5A所示，随着胆固醇浓度的增加，琼脂糖水凝胶中的颜色从浅蓝色变为深蓝色可以用肉眼轻易辨别。此外，琼脂糖水凝胶的颜色强度通过ImageJ软件进行测量（图5B）。颜色强度与胆固醇浓度的校准曲线在0.1 mM至0.7 mM范围内几乎呈线性关系。相应的线性方程为y = 0.32C（胆固醇）+ 2.03，相关系数为0.9954。与溶液测试相比，检查了用于血清胆固醇检测的便携式测定试剂盒的可靠性。将10倍稀释的血清样品直接加入试管中，并与琼脂糖水凝胶一起孵育。如图5C（插图）所示，五个不同的血清样品在琼脂糖水凝胶中显示出不同的颜色。通过参考图5B中相应的线性方程式，血清样本1-5中的胆固醇浓度经计算为3.93、3.35、2.96、5.25和4.74 mM，对应于人类血清中的胆固醇水平，约为2.86-5.98 mM。此外，测定试剂盒获得的结果与基于溶液测定的结果（R2 = 0.9953）非常吻合（图5C），表明定量评估人血清中胆固醇水平的可行性样品。图5.（A）琼脂糖水凝胶朝着不同浓度（从左至右：0–0.7 mM）的胆固醇标准的照片。（B）琼脂糖水凝胶的颜色强度与不同胆固醇浓度的关系。（C）在人血清样品中通过测定试剂盒测量的胆固醇浓度结果与基于溶液的测定法之间的相关性。插图：琼脂糖水凝胶对五个不同血清样品的照片。【陈述总结】作者开发出一种简单而灵敏的比色法，通过使用具有过氧化物酶样活性的PPy NPs检测血清中的胆固醇。通过与ChOx偶联，胆固醇的线性动态范围为0–100μM，LOD为3.5μM。此外，这种方法可以评估血清中的胆固醇水平，其结果与市售ELISA试剂盒的结果非常吻合。此外，构建了一种简单，便携式且无需仪器的测定试剂盒，用于检测血清样品中的胆固醇，为生物技术和临床诊断中的应用提供了良好的平台。参见文献：http://doi.org/10.1021/acsami.0c15900版权声明：「水凝胶」是由专业博士（后）创办的非赢利性学术公众号，旨在分享学习交流高分子聚合物材料学的研究进展。上述仅代表作者个人观点且作者水平有限，如有科学不妥之处，请予以下方留言更正。如有侵权或引文不当请联系作者修正。商业转载请联系编辑或顶端注明出处。感谢各位关注！发布于 2020-11-30 20:25胆固醇便携式设备湖南大学​赞同 1​​添加评论​分享​喜欢​收藏​申请

报名时有软性 Play counts 要求，重度 deranker 和 炸鱼 选手可能会被强制升级。

报名结束后，主办方会公布所有成功报名玩家的名单与对应分组。分组方式如下：

选手的 4k PP

EX

9500 及以上

S

7000 ~ 9499

A

4500 ~ 6999

B

如果选手的 4k pp 超过其组别的上限过多，可能将会被强制升级到更高的组别。

比赛工作人员 不能作为选手参加本次赛事。

赛事主办方可能会强制升级一些在其组别过于强大的选手。

赛事主办方保留禁止选手参加本次比赛的权力。

选手可以主动向主办方申请升降级，需要向主办方提供一些下一组别的成绩截图来获得许可。

获胜条件

在常规赛阶段，选手需要尽可能在更高的等级中获得更高的排名，以获得更高的分数。每轮可以获得的分数取决于选手在本轮的位次，位次取决于本轮所有谱面的单曲排名和。

根据每轮的排名有一个对应的基准分，而不同的组别有不同的加成倍率。积分的计算方式如下表：

选手在资格赛的最终排名取决于总共四轮的积分之和。排前24名的选手将可以参加季后赛。

前8名的选手将会进入季后赛胜者组，第9-24名的选手将会进入季后赛败者组。

如果计算总排名时出现重分情况，将会计算所有轮次的总排名和，排名和更小的在前。

在季后赛阶段，选手需要在一定数量的谱面中击败对手以胜出。数量视实际情况决定。

比赛流程

比赛开始前5分钟，裁判提前建好多人房间，选手必须在此期间进房。

房间设置为： Game mode: "osu!mania", Team mode: "Head-to-Head", Score mode: "ScoreV2"。房间必须按以下格式样例命名： GBC 2024 Spring: Lv.EX R1 | Sun 22.

允许使用的 Mod 为：NoFail, Hidden, FadeIn, Flashlight, Mirror。

裁判会按图池顺序依次选择谱面进行游玩，如果选手在比赛期间遇到了技术问题，可以在轮次打完之后请裁判补选谱面单独出分。

游戏卡顿延迟并不会被作为一个可行的理由。

即使需要在图池谱面轮换结束后重开某些谱面，也应该先完成图池其他谱面的出分。

在游戏开始后因故离开房间申请补分，每轮比赛最多一次，而且可能会被裁判拒绝。

禁止滥用此规则，如果裁判发现有选手故意利用此规则，裁判有权拒绝重赛请求。

如无特殊情况，在一个谱面上多次出分，只会记录第一次在主办方官方房间内的出分。

默认局间休息时间为 120秒 ，如果房间内选手均同意提前开始下一谱面出分并全部准备则裁判可以提前开局。

选手应该保持比赛流畅，严禁故意拖延。如选手过度的拖延时间，裁判可自行决定是否判罚。严禁通过犯规、侮辱或挑衅其他选手或工作人员、拖延时间或其他故意不当行为来扰乱比赛，如有违反将受到相应的惩罚。

比赛期间，必须尊重所有选手和工作人员，遵循裁判和主办方的指示，不得反对裁判和主办方最终决定。

比赛房间中的聊天室也受到 osu!规章制度 的约束，玩家在比赛房间中所有聊天信息均需遵守相应规则。

通过犯规或排名操纵来扰乱比赛将导致取消资格，任何此类选手都将被公布。

如有必要，裁判有权利自行决定规则的实施，并对比赛期间发生的事件有最终裁决权。

主办方有权要求选手开启直播或录像。

主办方保留修改规则的权利，任何类似修改将会提前宣布。

图池结构

每组各有四轮图池，每组每轮使用一个图池。

每个图池由 7 张谱面组成，这些谱面都将在 FreeMod 条件下游玩。

Freemod 允许的 mod 包括 No Fail, Hidden, Fade In, Flashlight, and Mirror.

图池中所包含的谱面键型并不固定。

日程信息

常规赛每个阶段都会进行两周。

EX组 与 S组 在同一个周末进行比赛，A组 与 B组 在同一个周末进行比赛。

所有的比赛默认都会在周六早 8 点到周日晚 12 点之间进行（UTC+08）。

主办方会在比赛开始前的一周提前提供每轮可供选择的的比赛时间段，尽量创造一个所有参赛选手都满意的时间安排。

如果你想在一个特定的时间打或某个特定时间没空比赛请提前告知主办方，主办方会尽量满足所有选手的要求，但不能保证全部实现。

时间不会安排到每周周日晚12点之后，除非这是无法避免的且比赛选手和主办方都同意。

即使需要，比赛也必须在下周三之前完成，更后面的补赛请求将被拒绝。

如无必要，请不要提交修改时间的申请。主办方保留拒绝修改时间的申请的权利。

季后赛

季后赛规则与常规赛大体相同。

主办方将会在常规赛结束后邀请常规赛排名最高的选手们参加季后赛。

选手门可以视个人情况不参加季后赛，席位将会顺延给后面的选手。

季后赛有 4 个单独的图池，每个图池有不同数量的不同类型的谱面。

阶段

谱面

8强赛 & 半决赛

6米，3混，3面，1TB

决赛 & 总决赛

7米，3混，4面，1TB

选手将拥有 2 分钟来保图，选图与ban图，选图后选手有 2 分钟的时间来准备。如果选手超时，那么过程如下：

如果在 ban 图或保图，那么此次 ban 图或保图作废。

如果在选图，裁判使用roll点指令从图池可用谱面中随机选择一张谱面进行游玩。

如果在准备期间，裁判会直接使用 !mp start 10 指令开始游戏倒计时。

双方选手每场比赛有一次可选的两分钟的技术暂停机会。可以用在选图ban图流程上。

可以在TB决胜局叫暂停，但是需要双方选手都同意才可以。

比赛开始前15分钟，裁判提前建好多人房间，选手必须在此期间进房。

房间设置为：游戏模式: "osu!mania", 分组方式: "Team Vs", 胜利条件: "ScoreV2". 房间名必须命名为：GBC 2024 Spr: ({PlayerA}) vs ({PlayerB})。

双方选手在房间频道里至少使用一次 !roll 指令进行掷骰子。

点数大的选手可以选择先保图或者先禁用图，另一方自动选择另一个选项。先保图的一方会先选图。

每位选手可以从图池中保护一张谱面，在接下来整场比赛期间此谱面不可被禁用。

每位选手可以从图池中禁用一张谱面，在接下来整场比赛期间此谱面不可被选择。

每位选手轮流从图池中选择一张谱面并进行比赛。

如果在一张图中出现平局，这张图将被重开。一张图将不会重开超过两次。

每个选手最多被允许一次由于掉线或其他技术性问题造成的重开（请及时在游戏内发送信息通知裁判要求重开）。

该次比赛还没超过30秒和全图的1/4。

在比赛重开时必须使用与之前相同的mod和图。

请务必在比赛前确保不会出现技术性问题。

如有必要，裁判有权利自行决定规则的实施，并对比赛期间发生的事件有最终裁决权。

主办方有权要求选手开启直播或录像。

主办方保留修改规则的权利，任何类似修改将会提前宣布。

Gameplay

Fix beatmap offsets not being applied correctly to extreme rate changes (#27243 by @myQwil)

Gameplay (osu!)

Fix classic skins incorrectly applying scaling factor to approch circles (#27286 by @peppy)

In triangles and argon, we expanded hitcircles to take up the full 128 px which are clickable, but still use the old approach circle sprite. To make it feel correct (ie. disappear as it collides with the hitcircle, not when it overlaps the border) we need to expand it slightly.

Note that this fix only affects classic/legacy skins.

Before

After

Fix classic skin follow circles animating from incorrect starting point (#27288 by @peppy)

Performance

Reduce osu editor allocations with many objects selected (#27249 by @EVAST9919)

Reduce mania editor allocations with many objects selected (#27275 by @EVAST9919)

Apply padding to GridContainers directly where possible (#27278 by @EVAST9919)

Fix allocations in SliderInputManager.updateTracking (#27230 by @EVAST9919)

Settings

Remove Veldrid OpenGL renderer, always use (legacy) GLRenderer (ppy/osu-framework#6193 by @smoogipoo)

Spurred by people using this renderer, likely because "legacy" has a bad connotation associated with it (e.g. https://discord.com/channels/188630481301012481/1097318920991559880/1209220240383418438).

This forces GLRenderer ("legacy") to be used even when the OpenGL renderer type is selected.

Song Select

Fix beatmap carousel ordering not matching expectations (#27292 by @bdach)

Broke in yesterday's release, oops.

UI

Localise storage error popup dialog (#27258 by @Loreos7)

Gameplay (osu!)

Fix relax mod not respecting tracking state of sliders when triggering actions (#26763 by @frenzibyte)

Create key-presses when watching osu!stable "Relax" replays (#27145 by @tsunyoku)

osu!stable does not record key presses onto replays with Relax, so attempting to watch them back in lazer didn't work historically.

Smaller changes

Fix cursor ripples displaying on release positions in replays (#27200 by @frenzibyte)

Gameplay (osu!catch)

Never flip fruit on plate (#27165 by @frenzibyte)

Limit vertical visibility of osu!catch playfield to an aspect ratio of 4:3 (#27162 by @frenzibyte)

Gameplay (osu!mania)

Add progressive coverage for mania's Hidden and FadeIn mods (#27068 by @smoogipoo)

This restores progressive coverage that HD and FI had in osu!stable, and adds a new mod ManiaModCover / CO which allows setting a custom cover.

Smaller changes

Use SlimReadOnlyListWrapper for KeyBindingContainer.PressedActions (ppy/osu-framework#6185 by @EVAST9919)

Platform

Suggest to update only if the latest release is available for the current platform (#26930 by @Susko3)

We've had few releases lately where mobile isn't working / is crashing, so the mobile release was pulled. Unfortunately, the game would still send an update notification, leading to many people opening issues about the update not being available for their platform.

This fixes that.

Fix holding keys before gameplay starts resulting in incorrect input (ppy/osu-framework#6101 by @frenzibyte)

Fade hold-for-menu button out completely on non-touch devices (#26542 by @peppy)

Simplify gameplay pause sequence (#26605 by @peppy)

This removes the frequency ramp on pausing. This was something I was personally behind implementing and working to keep around, but nuking in favour of simplifying the process for now. In discussing with nekodex we both agree there is a better way forward than this.

This lays groundwork for doing other things, like allowing seeking during replay pause, and changing the way offsets work without worrying about the weird application considerations from the pause ramp effect.

Fix gameplay elements not correctly offsetting to avoid per-ruleset skin layout (#26609 by @peppy)

Change S rank to require no miss (#26630 by @peppy)

This is a change for osu!/osu!taiko to match stable. It's not final. We're just giving people what they are used to for now. If you're about to comment about how you disagree with this, then please make sure to search first and contribute to an existing conversation.

De-dupe displayed hits in judgement counter (#26540 by @peppy)

Only display offset toast when in local gameplay (#26543 by @peppy)

Implement shaders for ArgonHealthDisplay (ppy/osu-resources#302 by @EVAST9919)

Fix argon health bar showing "miss" bar for bananas (#26561 by @peppy)

Gameplay (osu!)

Fix flashlight not dimming if slider head is hit early (#26576 by @bdach)

Fix cursor scale animation not matching stable on classic skins (#26567 by @peppy)

Adjust slider tick / end miss animations to be shorter (#26668 by @peppy)

There's still a lot of feedback that these are noisy and get in the way. As a recap, you can already skin these out using sliderendmiss and sliderendtick, but adding these in a classic skin is a bit of a pain in the ass, so I want to make the defaults usable for most users.

We'll continue to iterate based on feedback!

Adjust slider tick / end miss visuals to be less noisy (#26703 by @peppy)

More subtle, less noisy, but still should describe the misses quite well.

I toyed with bringing across the stable behaviour of ticks not fading out but people preferred this direction, so let's stick with it.

Smaller changes

Fix pop-in scale transition in resume overlay affecting input area (#26545 by @frenzibyte)

Fix touch device not always activating when it should (#26575 by @bdach)

Adjust legacy slider misses to be smaller again (ppy/osu-resources#304 by @peppy)

People are still complaining so I want to first try to make them more subtle.

Gameplay (osu!mania)

Fix key overlay not showing special key in the right place (#26589 by @peppy)

Gameplay (osu!taiko)

Fix taiko maps containing only drum rolls / swells not being passable without mods (#26578 by @bdach)

Change the input drum width to be consistent across all skins (#26632 by @frenzibyte)

Up until now, the input drum width was variable per skin, which results in the overall gameplay width changing based on skin. This has been discussed to be quite bad and must not be the case (see discord).

The constant width for the input drum has been defined to be 180px, visually matching osu!stable on classic skin. Default skins have been altered slightly to respect that width (basically set its height with respect to width rather than the opposite).

Change hit target position in osu!taiko to always match stable (#26634 by @frenzibyte)

Move osu!taiko playfield down a nudge to match stable visually (#26635 by @frenzibyte)

Remove rounding of slider velocity (when applied as scroll speed) (#26616 by @peppy)

This fixes some beatmaps using very precise slider velocities to create a speed ramp from looking too "jumpy".

Fix osu!taiko's scroll speed not matching stable expectations (#26781 by @frenzibyte)

This finally brings osu!taiko in line with scroll speed on stable, even when "classic" mod is not applied.

Increase slider tails' score to 150 points (up from 30) (#26248 by @smoogipoo)

@Bubbleman532, @Zyfarok, and others in the community have mentioned that the changes to sliders (tails not affecting the slider's main judgement, because that judgement is now on the head) have made tails not worth as much anymore, and removes the need to aim sliders on higher SR maps that very rarely have any ticks in sliders.

This PR makes tails worth 150 points, compared to the 30 points of a normal tick.

Scoring

Fix score conversion incorrectly assuming zero combo score in certain cases (#26440 by @bdach)

Fix incorrect score conversion on selected beatmaps due to incorrect difficultyPeppyStars rounding (#26471 by @bdach)

Fixes issue that occurs on about 245 beatmaps[^1] and was first described by me on discord and then rediscovered again during work on #26405.

Song Select

Improve speed of beatmap carousel load when scrolling (#26385 by @peppy)

The preload numbers are still on the conservative side. We can probably adjust these based on the system the game is running on in the future. Or across the board. But this should improve the overall responsiveness of carousel loading, something that's been bugging me for quite a while now (and not just me)

Smaller changes

Fix mod score multiplier rounding to 1.00x with specific mod combinations (#26140 by @CaffeeLake)

Remove scores from song select leaderboard when leaving the screen (#26410 by @peppy)

Noticed they would disappear-then-appear after visiting the ranking screen. Which feels very weird.

Fix crash when clicking osu! logo in song select immediately after exiting (#26437 by @bdach)

Editor

Add visual offset to better align editor waveforms with expectations (#26136 by @peppy)

In preparation for locking in better audio constants in lazer, let's fix the editor waveform looking completely misaligned.

This adds a visual-only offset to better align the editor waveform (in the timeline and on the timing screen) with osu! community expectations. With this change, visual-based timing is feasible, and assuming done correctly, should be accurate within 2 ms.

Fix editor timing mode not handling undo/redo correctly (#26141 by @peppy)

When undoing, selection would be lost, and (kind of as a result) the controls on the right of the screen would enter a detached state where they don't update correctly. Quite annoying when you're making changes.

Framework

Fix audio being initialised more than once unnecessarily (ppy/osu-framework#6090 by @peppy)

Bump OpenTabletDriver to 0.6.4.0 (ppy/osu-framework#6086 by @X9VoiD)

Added support for:

Gaomon GM116HD

Huion Kamvas 22

VEIKK VK1060PRO

Wacom CTC-4110WL

Wacom CTC-6110WL

Wacom DTH-1320

Huion H1060P

Huion H420x

Huion H950P

Huion Kamvas 20

Huion Kamvas Pro 24 (4K)

Kamvas Pro 13 (2.5k)

UGEE S640

Also:

Huion Q11K: Fix digitizer specifications

XP-Pen Star 05 V3: Fix digitizer specifications

Fix "Windows Ink" events being handled as touch events (ppy/osu-framework#5309 by @Susko3)

This fixes some tablet devices incorrectly enabling the "touch device" mod.

Smaller changes

Rename concept of "global" mixer with "fallback" (ppy/osu-framework#6091 by @peppy)

Add basic global statistics for input handler events (ppy/osu-framework#6087 by @Susko3)

Add low latency initialisation support on windows by directly interacting with WASAPI (ppy/osu-framework#6088 by @peppy)

Seems good, but had issues.

Disable WASAPI initialisation mode for now (ppy/osu-framework#6093 by @peppy)

Need some more time to test this out. As I kinda expected, it doesn't work well across the board.

Update framework (#26159 by @peppy)

Gameplay

Bail from score submission if audio playback rate is too far from reality (#26138 by @peppy)

Handles cases where audio drivers aren't working as expected.

Gameplay (osu!)

Add new mod "Depth" (#25653 by @EVAST9919)

Update argon and triangles slider tick/end miss to match display style (#26120 by @peppy)

Add classic skin sprites for slider tick and slider end misses (#26117 by @peppy)

A lot of complaints asking for disable on the new elements. Mostly because it was confusing to just downscale the normal miss.

Now they get their own sprites. And as a result it's skinnable for the people that are really adverse to change. You can skin via slidertickmiss@2x.png and sliderendmiss@2x.png.

CleanShot.2023-12-25.at.08.12.17.mp4

CleanShot.2023-12-25.at.08.13.40.mp4

Fix spinner max bonus sound playing when seeking in replay (#26170 by @rushiiMachine)

Force minimum cursor size for click-to-resume screen (#26148 by @rushiiMachine)

On cursor sizes below 0.3x it becomes exceedingly difficult to quickly locate and then accurately click the resume cursor on the pause overlay as it could as big as a handful of pixels. In the event the cursor aligns somewhere on top of or close to the text, it becomes nearly impossible to find it as it's even the same color.

This clamps the minimum cursor size to 1x for the resume overlay, which is way more comfortable and less likely to cause the player to miss afterwards (note that not the entire cursor aura is interactable, only about 2/3s) and more closely resembles stable.

Smaller changes

Add new sprites for slider end / tick misses (ppy/osu-resources#300 by @peppy)

Gameplay (osu!catch)

Fix catch objects not being clamped to playfield bounds (#26158 by @bdach)

Gameplay (osu!mania)

Make mania scroll speed independent of hit position (#26131 by @smoogipoo)

This fixes skins using a custom "HitPosition" having incorrect scroll speed.

Main Menu

Add support for displaying online images on main menu (#26172 by @bdach)

Move menu tips to main menu (#26182 by @peppy)

Show supporter love message at main menu and remove the disclaimer screen (#26183 by @peppy)

Goodbye disclaimer screen!

Settings

Always show settings section text on buttons (#26147 by @peppy)

Was really annoying to decode the icons quickly. Now text always shows.

Implement automatic suggestion of global audio offset based on last plays (#26169 by @bdach)

This control takes the place of the existing audio offset slider in game settings.

This is supposed to be a crude something to be in place by next year while the work on the real "offset wizard" can be postponed just a little bit longer.

Song Select

Fix rewind sometimes incorrectly selecting the same beatmap (#26127 by @ntransw)

UI

Update icons game-wide (#26167 by @bdach)

main menu, top level

main menu, play submenu

main menu, edit submenu

settings

editor

All editorial decisions ("why is this variant of the icon used?" "why are the icons smaller / have more padding?") are either mine alone or/and were made in line with feedback from @peppy.

All traces of hexacons have been erased. May they rest well. Note that this also affects overlay headers since they are weirdly conjoined to toolbar icons for whatever reason. But I think it's fine.

Toolbar design iteration (#26168 by @peppy)

Takes some inspiration from flyte's newer designs but also makes some changes I feel works well. Iterative and not final.

Update popup dialog design (#26187 by @peppy)

Had to be done. I got irked every time these came up.

As usual, disclaimer that this is an iterative design and will probably be replaced in the future.

Smaller changes

Add new icon assets (ppy/osu-resources#301 by @bdach)

osu!

A free-to-win rhythm game. Rhythm is just a click away!

This is the future – and final – iteration of the osu! game client which marks the beginning of an open era! Currently known by and released under the release codename "lazer". As in sharper than cutting-edge.

Status

This project is under constant development, but we do our best to keep things in a stable state. Players are encouraged to install from a release alongside their stable osu! client. This project will continue to evolve until we eventually reach the point where most users prefer it over the previous "osu!stable" release.

A few resources are available as starting points to getting involved and understanding the project:

Detailed release changelogs are available on the official osu! site.

You can learn more about our approach to project management.

Track our current efforts towards improving the game.

Running osu!

If you are just looking to give the game a whirl, you can grab the latest release for your platform:

Latest release:

Windows 10+ (x64)

macOS 12+ (Intel, Apple Silicon)

Linux (x64)

iOS 13.4+

Android 5+

You can also generally download a version for your current device from the osu! site.

If your platform is unsupported or not listed above, there is still a chance you can run the release or manually build it by following the instructions below.

For iOS/iPadOS users: The iOS testflight link fills up very fast (Apple has a hard limit of 10,000 users). We reset it occasionally. Please do not ask about this. Check back regularly for link resets or follow peppy on twitter for announcements. Our goal is to get the game on mobile app stores in early 2024.

Developing a custom ruleset

osu! is designed to allow user-created gameplay variations, called "rulesets". Building one of these allows a developer to harness the power of the osu! beatmap library, game engine, and general UX for a new style of gameplay. To get started working on a ruleset, we have some templates available here.

You can see some examples of custom rulesets by visiting the custom ruleset directory.

Developing osu!

Prerequisites

Please make sure you have the following prerequisites:

A desktop platform with the .NET 8.0 SDK installed.

When working with the codebase, we recommend using an IDE with intelligent code completion and syntax highlighting, such as the latest version of Visual Studio, JetBrains Rider, or Visual Studio Code with the EditorConfig and C# plugin installed.

Downloading the source code

Clone the repository:

git clone https://github.com/ppy/osu

cd osu

To update the source code to the latest commit, run the following command inside the osu directory:

git pull

Building

From an IDE

You should load the solution via one of the platform-specific .slnf files, rather than the main .sln. This will reduce dependencies and hide platforms that you don't care about. Valid .slnf files are:

osu.Desktop.slnf (most common)

osu.Android.slnf

osu.iOS.slnf

Run configurations for the recommended IDEs (listed above) are included. You should use the provided Build/Run functionality of your IDE to get things going. When testing or building new components, it's highly encouraged you use the osu! (Tests) project/configuration. More information on this is provided below.

To build for mobile platforms, you will likely need to run sudo dotnet workload restore if you haven't done so previously. This will install Android/iOS tooling required to complete the build.

From CLI

You can also build and run osu! from the command-line with a single command:

dotnet run --project osu.Desktop

When running locally to do any kind of performance testing, make sure to add -c Release to the build command, as the overhead of running with the default Debug configuration can be large (especially when testing with local framework modifications as below).

If the build fails, try to restore NuGet packages with dotnet restore.

Testing with resource/framework modifications

Sometimes it may be necessary to cross-test changes in osu-resources or osu-framework. This can be quickly achieved using included commands:

Windows:

UseLocalFramework.ps1

UseLocalResources.ps1

macOS / Linux:

UseLocalFramework.sh

UseLocalResources.sh

Note that these commands assume you have the relevant project(s) checked out in adjacent directories:

|- osu // this repository

|- osu-framework

|- osu-resources

Code analysis

Before committing your code, please run a code formatter. This can be achieved by running dotnet format in the command line, or using the Format code command in your IDE.

We have adopted some cross-platform, compiler integrated analyzers. They can provide warnings when you are editing, building inside IDE or from command line, as-if they are provided by the compiler itself.

JetBrains ReSharper InspectCode is also used for wider rule sets. You can run it from PowerShell with .\InspectCode.ps1. Alternatively, you can install ReSharper or use Rider to get inline support in your IDE of choice.

Contributing

When it comes to contributing to the project, the two main things you can do to help out are reporting issues and submitting pull requests. Please refer to the contributing guidelines to understand how to help in the most effective way possible.

If you wish to help with localisation efforts, head over to crowdin.

We love to reward quality contributions. If you have made a large contribution, or are a regular contributor, you are welcome to submit an expense via opencollective. If you have any questions, feel free to reach out to peppy before doing so.

Licence

osu!'s code and framework are licensed under the MIT licence. Please see the licence file for more information. tl;dr you can do whatever you want as long as you include the original copyright and license notice in any copy of the software/source.

Please note that this does not cover the usage of the "osu!" or "ppy" branding in any software, resources, advertising or promotion, as this is protected by trademark law.

Please also note that game resources are covered by a separate licence. Please see the ppy/osu-resources repository for clarifications.

聚吡咯簡介

純吡咯單體常温下呈現無色油狀液體，是一種C，N五元雜環分子，沸點是129.8℃，密度是0.97g/cm，微溶於水。性質：研究和使用較多的一種雜環共軛型導電高分子，通常為無定型黑色固體,以吡咯為單體，經過電化學氧化聚合製成導電性薄膜，氧化劑通常為三氯化鐵、過硫酸銨等。或者用化學聚合方法合成,電化學陽極氧化吡咯也是製備聚吡咯的有效手段。是一種空氣穩定性好，易於電化學聚合成膜的導電聚合物，不溶不熔。它在酸性水溶液和多種有機電解液中都能電化學氧化聚合成膜，其電導率和力學強度等性質與電解液陰離子、溶劑、pH值和温度等聚合條件密切相關。導電聚吡咯具有共軛鏈氧化、對應陰離子摻雜結構，其電導率可達102～103S/cm，拉伸強度可達50～100MPa及很好的電化學氧化-還原可逆性。導電機理為：PPy結構有碳碳單鍵和碳碳雙鍵交替排列成的共軛結構，雙鍵是由σ電子和π電子構成的，σ電子被固定住無法自由移動，在碳原子間形成共價鍵。共軛雙鍵中的2個π電子並沒有固定在某個碳原子上，它們可以從一個碳原子轉位到另一個碳原子上，即具有在整個分子鏈上延伸的傾向。即分子內的π電子雲的重疊產生了整個分子共有的能帶，π電子類似於金屬導體中的自由電子。當有電場存在時，組成π鍵的電子可以沿着分子鏈移動。所以，PPy是可以導電的。在聚合物中，吡咯結構單元之間主要以α位相互聯接，當在α位有取代基時聚合反應不能進行。用電化學氧化聚合方法可以在電極表面直接生成導電性薄膜，其電導率可以達到102S/cm，且穩定性好於聚乙炔。聚吡咯的氧化電位比其單體低約1V左右。聚吡咯也可以用化學摻雜法進行摻雜，摻雜後由於反離子的引入，具有一定離子導電能力。聚吡咯除了作導電材料使用，如作為特種電極等場合外，還用於電顯示材料等方面，作為線性共軛聚合物，聚吡咯還具有一定光導電性質。小陰離子摻雜的聚吡咯在空氣中會緩慢老化，導致其電導率降低。大的疏水陰離子摻雜的聚吡咯能在空氣中保存數年而無顯著的變化。

聚吡咯應用範圍

聚吡咯可用於生物、離子檢測、超電容及防靜電材料及光電化學電池的修飾電極、蓄電池的電極材料。此外，還可以作為電磁屏蔽材料和氣體分離膜材料，用於電解電容、電催化、導電聚合物複合材料等，應用範圍很廣。具體如下：（1）離子交換樹脂：相比於傳統的離子交換樹脂,這種材料把電化學和離子交換結合在一起,能方便的再生和減小能耗、降低污染。（2）生物材料：PPy具有良好的生物相容性，在電刺激下導電聚合物可以調節細胞的貼附、遷移、蛋白質的分泌與DNA的合成等過程，使其在生物醫學領域有着廣泛的應用前景。（3）質子交換膜：質子交換膜作為質子交換膜燃料電池的核心部件，直接決定着燃料電池的性能。將PPy引入其中製備複合型質子交換膜有助於提高複合膜的熱穩定性、阻醇性和溶脹性等。（4）電催化：PPy膜具有獨特的摻雜和脱摻雜性能，可以有針對性的摻雜進許多具有對反應物有催化作用的分子或離子，提供電催化效率和實際應用價值。（5）二次電池的電極材料：PPy具有較高的電導率、環境穩定性好、可逆的電化學氧化還原特性以及較強的電荷貯存能力，是一種理想的聚合物二次電池的電極材料（6）金屬防腐：PPy膜對金屬的保護起到鈍化和屏蔽作用，提高了金屬基體的腐蝕電位，降低了腐蝕速率。

聚吡咯製備及其原理

聚吡咯可由吡咯單體通過化學氧化法或者電化學方法製得。化學聚合是在一定的反應介質中通過採用氧化劑對單體進行氧化或通過金屬有機物偶聯的方式得到共軛長鏈分子並同時完成一個摻雜過程。該方法的合成工藝簡單，成本較低，適於大量生產。使用化學法製備聚吡咯時的產物一般為固體聚吡咯粉末，即難溶於一般的有機溶劑，機械性能也較差不易進行加工。合成聚吡咯產品是的機理：首先，當體系中有氧化劑存在時，呈電中性的一個聚吡咯單體分子會在氧化劑的作用下被氧化失去一個電子，變成陽離子自由基。然後兩個陽離子自由基在體系中碰撞結合成含有兩個陽離子自由基的雙陽離子二聚吡咯，此時的雙陽離子在體系中經過歧化作用生成一個呈電中性的二聚吡咯。電中性的二聚吡咯又會與體系中的陽離子自由基相互結合生成三聚吡咯的陽離子自由基，經過歧化作用而生成三聚體的聚吡咯，週而復始最終生成了長分子鏈的聚吡咯。電化學聚合是在電場作用下，採用電極電位作為聚合反應所需要的能量，經過一段時間的反應後會在電極表面沉澱一層聚合物從而得到共軛高分子膜。通過控制聚合條件如電解液種類、吡咯單體的濃度、溶劑、聚合電壓、電流大小和温度等因素可製備具有各種不同形貌和性能的高聚物膜。進行電化學聚合時一般以鉑、金、不鏽鋼、鎳等惰性金屬或導電玻璃、石墨和玻炭電極等作為電極使用。在使用電化學方法制備聚吡咯時的聚合機理與用化學氧化法制備時的機理相似，也可以用自由基機理來解釋：首先，吡咯單體分子在電場的作用下，會在電極的表面失去電子而成為陽離子自由基，然後自由基會與另一單體相互結合而成為吡咯的二聚體。經過鏈增長步驟，最終得到聚吡咯大分子鏈。通常來説，使用化學氧化聚合法或電化學聚合法制備聚吡咯時，得到的產品都是黑色的固體，在使用化學氧化聚合法時製備的聚吡咯的產物一般是黑色粉末，而通過電化學聚合法則會在電極表面得到一層PPy薄膜。
