基于铅笔芯和多巴胺电聚合膜固定葡萄糖氧化酶的高灵敏酶电极
A Sensitive Enzymatic Electrode for Glucose Based on 8B Pencil Lead and Dopamine Polymer for Immobilization of Glucose Oxidase
【摘要】 市售8B铅笔芯经镀铂处理后,将葡萄糖氧化酶共沉积到新型多巴胺电氧化聚合膜中,最外层再修饰聚邻氨基酚薄膜,研制出新型葡萄糖氧化酶修饰电极用于葡萄糖检测.
【Abstract】 A new enzymatic electrode for glucose determination was developed by codepositing glucose oxidase into the polymer from electrochemical oxidation of dopamine(DA) on a Pt-modified 8B pencil lead electrode,followed by electrochemically depositing an outer poly(o-aminophenol) film,which exhibited very good performance,such as fast current response,high sensitivity,broad linear range,excellent stability and good anti-interferent ability for ascorbic acid and uric acid.
