A drug-loaded flexible substrate improves the performance of conformal cortical electrodes
皮质电极是刺激和/或记录神经系统电活动的有力工具. 然而, 外科植入电极所导致的不可避免的伤口带来了与外源性物质暴露相关的细菌感染和炎症反应风险. 此外, 伤口区域的炎症可能会因细菌感染而急剧恶化. 这些后果不仅可能导致皮质电极植入失败, 还可能威胁患者生命. 在此, 我们制备了负载抗生素四环素 (TC) 和抗炎药物地塞米松 (DEX) 的细菌纤维素 (BC) 水凝胶, 并将其作为皮质电极的柔性基底. 负载的药物可...
