A new amperometric biosensor based on Fe3O4/polyaniline/laccase/chitosan biocomposite-modified carbon paste electrode for determination of catechol in tea leaves.
本研究开发了一种基于Paraconiothyrium variabile来源漆酶(laccase, Lac)的新型生物传感器,用于儿茶酚(catechol)检测。纯化的漆酶无需其他交联剂,通过一步电沉积被包埋于Fe3O4/聚苯胺/壳聚糖(Fe3O4/PANI/CS)生物复合膜中,并修饰于碳糊电极(CPE)表面。采用扫描电子显微镜(S...
