持久存留于血液中的传感器Sensors That Last In Blood
➀ 传统生物传感器因血液中快速降解问题，难以实现长期实时监测；
➁ 受肠道结构启发，研究者开发了SENSBIT系统，采用3D纳米多孔金表面和仿黏膜涂层提升稳定性；
➂ 该传感器在人体血清中1个月保留70%以上信号，并在活体大鼠血管中工作一周，为早期感染检测和精准医疗提供突破。
➀ Traditional biosensors face challenges in blood due to rapid degradation, limiting real-time monitoring capabilities;
➀ Researchers developed the SENSBIT system, inspired by the gut's protective structure, using a 3D nanoporous gold surface and mucosal-like coating for enhanced stability;
➂ The sensor retained over 70% signal after a month in human serum and functioned for a week in live rats, enabling early infection detection and advancing personalized healthcare.
