cathodic trigger that reduces PEDOT while enabling the drug to diffuse. This approach has several disadvantages including, for instance, the release of contaminants mainly due to PEDOT decomposition during electrochemical release. Herein we describe a new strategy based on the formation of a chemical linkage between the drug and the conductive polymer. In particular, dexamethasone was successfully integrated
PEDOT(聚(3,4-亚乙基二氧噻吩))是生物医学应用(如神经记录和刺激)中最有前途的电极材料之一,这归功于其增强的生物相容性和电子特性。通过PEDOT进行的药物输送通常是通过在电沉积过程中掺入药物作为掺杂剂来实现的,随后的释放可以通过施加减少PEDOT的阴极触发来促进,同时使药物能够扩散。该方法具有若干缺点,例如包括主要由于电化学释放期间的PEDOT分解而导致的污染物释放。在这里,我们描述了一种基于药物与导电聚合物之间化学键形成的新策略。特别是,地塞米松已成功整合到新型电聚合的PEDOT-Dex复合材料中,
