lead pencil
3.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.
