| 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. |
