Poly (pyrrole-co-N-methyl pyrrole) for application to cholesterol sensor
Source abstract
Abstract
Cholesterol oxidase (ChOx) has been electrochemically entrapped onto p-toluene sulphonate (PTS) doped poly (pyrrole-co-N-methyl pyrrole) (1:1) on indium-tin-oxide (ITO) glass plates. This ChOx-copolymer-PTS/ITO bioelectrode has been characterized using cyclic voltammetry (CV), Fourier transform infrared (FTIR) spectroscopy, UV-visible spectroscopy, scanning electron microscopy (SEM) techniques. The cholesterol bioelectrode shows response time of 19 s, linearity from 50 to 400 mg/dL as a function of cholesterol concentration. It exhibits optimum pH range between 6.5 and 7.5, shelf-life of up to 6 weeks at 4 °C and shows almost undisturbed response in presence of interferents like ascorbic acid, uric acid and glucose.
