Abstract
A sensor for glucose formed in a one-step process is described based on a new doped polyindole film coated onto a platinum surface; a polymer-entrapped glucose oxidase electrode can be operated as an amperometric glucose sensor. The new glucose sensor has fast response time (25–40 s) with high storage and operational stability ( > 35 days). Electrochemical rate constants for the new enzyme electrode have been calculated using the expressions derived by Albery et al.(J. Chem. Soc., Faraday Trans. 1, 1986, 82, 1033). It has been found that unsaturated enzyme kinetics are rate-limiting for conducting polymer-coated enzyme electrodes formed in a one-step process.This publication has 2 references indexed in Scilit:
