Chinese researchers have developed a multifunctional electrode coating that addresses key challenges in long-term brain-computer interface (BCI) implantation, including signal loss and tissue adhesion, bringing BCI one step closer to clinical application, the Global Times learned from the research team behind the findings on Sunday. 
As an emerging field combining neuroscience and artificial intelligence (AI), BCI faces a major challenge of ensuring long-term compatibility between electrodes and brain tissue. Previous clinical trials showed that immune responses could cause implanted electrodes to retract after just three months, severely reducing signal quality and the number of available channels. 
This problem stems from chronic inflammation triggered by implants, which creates insulating scar tissue around electrodes and separates them from neurons. Irreversible adhesion between electrodes and brain tissue after long-term implantation also makes device removal risky, potentially causing brain injury during follow-up surgeries.
Experiments showed that flexible neural electrodes coated with this material could operate stably in the brain for more than 300 days and could be safely removed without causing damage. This means the universal coating technology can make electrodes not only operate stably over the long term but can also be safely removed and replaced after aging, paving the way for long-term BCI applications.
Developed by the research team led by Zhang Wei at the Technical Institute of Physics and Chemistry, Chinese Academy of Sciences, associated with Beijing Tiantan Hospital, Shanghai Institute of Microsystem and Information Technology and NeuroXess, a high-tech life science company specializing in BCI technologies, the cationic alternating peptide electrode coating preserves electrode flexibility and conductivity, while offering antibacterial, anti-protein adsorption and immune-rejection-inhibiting functions. 
A 300-day animal study showed the coating's effectiveness. Bare electrodes experienced a sharp loss of recording capability after 90 days of implantation and could barely detect neuronal signals after 300 days. In contrast, coated electrodes maintained stable recording channels and consistently captured neural signals above 155 microvolts. 
In terms of neural modulation, after 300 days of implantation, conventional electrodes required a current of 100 microamps to induce weak limb responses, while coated electrodes triggered clear movements with only 2 microamps, improving modulation efficiency by 50 times. 
Notably, the removal tests highlighted a key advantage of the coating that electrodes no longer form irreversible bonds with brain tissue. In the experiments, the coated electrodes were removed intact, with minimal damage to the surrounding brain tissue, Zhang told the Global Times on Sunday.
。这位世锦赛亚军接连打出61分、132分、103分、139分、113分单杆，一路轰出5比0大比分领先，全程未让塞尔特拿到一分。第六局由墨菲率先上手得分，但他没能一杆清台，塞尔特终于拿下本场个人首分。第五局墨菲进攻行云流水，一红一黑不断入袋，现场观众发出惊呼赞叹，可惜第15颗黑球停在袋口没进，与147满分杆失之交臂。

B | 至此墨菲的连续无对手得分定格在607分，一举刷新“火箭”奥沙利文此前创下的纪录。

C | 2014年大师赛上，奥沙利文对阵里奇·沃顿曾连续轰下556分、对手一分未得，这项纪录尘封了12年之久。

D | 墨菲拿下第六局、以6比0横扫塞尔特，复刻了2014年奥沙利文在亚历山德拉宫6比0大胜沃顿的场面。根据英国《地铁报》的说法：“客观来说，中国举办赛事的台呢、球袋条件相比英国本土赛事更容易打出高分，球袋袋口更宽松，选手更容易连续上分。

E | 但所有参赛选手面对的都是同款球台，抛开场地条件不谈，墨菲本场发挥依旧堪称惊艳。”这位“魔术师”晋级16强后，下一轮对手是肖国栋；中国选手肖国栋在首轮比赛中6比3击败安东尼·麦克吉尔。43岁的墨菲似乎已经走出5月克鲁斯堡世锦赛决赛决胜局不敌吴宜泽的失意阴霾。今年世锦赛上，这位英格兰老将发挥十分出色，但最终以17比18惜败于22岁的中国新星，与个人第二座世锦赛冠军擦肩而过。本赛季二人再度交手，墨菲上海大师赛5-6再负吴宜泽。墨菲早年的绰号是“稳定先生”，打法均衡，极少波动；后来“魔术师”绰号深入人心，母球控制登峰造极，擅长多库绕球、极限薄球、刁钻翻袋，看似无解的局面总能打出意想不到的解球与进攻，观感如同魔术变戏法。另外，与吴宜泽这种依赖准度的准神不同，墨菲衔接能力出色，战术思路灵活，创造力十足，经常有观众预判不到的构思。
