Molecularly imprinted electrochemical biosensor based on Fe@Au nanoparticles involved in 2-aminoethanethiol functionalized multi-walled carbon nanotubes for sensitive determination of cefexime in human plasma.
本研究开发了一种基于 Fe@Au 核壳纳米粒子(Fe@AuNPs)与 2-氨基乙硫醇(2-AET)功能化多壁碳纳米管(f-MWCNs)修饰玻碳电极的分子印迹电化学生物传感器,用于灵敏测定头孢克肟(cefexime, CEF)。首先通过重氮盐电聚合和还原在玻碳电极表面构建对氨基苯基界面,再经 EDC 共价连接 2-AET-f-MWCN...
