Detection of sterigmatocystin based on the novel Aflatoxin- Oxidase/chitosan-single-walled carbon nanotubes/poly-o- phenylenediamine modified electrode
黄曲霉毒素氧化酶/壳聚糖-单壁碳纳米管/聚邻苯二胺修饰电极对杂色曲霉素的检测

A sensitive electrochemical biosensor based on Aflatoxin-Oxidase (AFO) was developed for detection of sterigmatocystin (ST).The enzyme was immobilized on chitosan-single-walled carbon nanotubes (CS-SWCNTs) hybrid film,which attached to the poly-o-phenylenediamine (POPD)-modified Au electrode.The fabricated procedures of the biosensor were characterized with atomic force microscopy (AFM),fourier transform-infrared spectroscopy (FT-IR),and electrochemical impedance spectroscopy (EIS).The cyclic voltammetric r...
