Abstract

The emergence of non-enzymatic glucose sensing (NEGS) received massive attention in the biosensors application because of the selectivity, sensitivity and low cost. The development of NEGS using Conductive Polyaniline Nanosheets (CPANINS) by in-situ polymerization using the structure directing agent (SDA) have summarized in the present study. XRD, FTIR, UV-Visible Spectroscopy and Field emission scanning electron microscopy (FESEM) characterized the structural, optical and morphology studies of the obtained CPANINS. The CPANINS have coated on the screen-printed electrode (SPE) for the investigation of electrochemical behaviour. The CPANINS/SPE exhibited a remarkable sensitivity 2003.5 mu A/mMcm(2) towards the oxidation of glucose with a broad liner range 1-1000 mu M, detection limit 0.043 lM (S/N = 3) and glucose oxidation with fast response time (T-response 1 s). The CPANINS showed better selectivity towards the glucose oxidation. As such, the proposed CPANINS could be part of the development of sustainable, eco-friendly, mere and low-cost glucose sensing devices. Published by Elsevier B.V.
