Abstract

Poly(2-methoxyaniline) microspheres (P2MA) were prepared by oxidative polymerization method using potassium persulphate and β-naphthalenesulphonic acid (NSA) as an oxidizing agent and dopant respectively. The spectral, morphological, and electrochemical characteristics of P2MA microspheres were determined from the results of Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, UV-Vis spectroscopy, scanning electron microscopy (SEM) and cyclic voltammetry (CV). The electrochemical sensing property of P2MA microspheres were studied by CV and chronoamperometry (CA) using uric acid (UA) as an analyte. The calibration curve for UA was obtained over the range of 6.6 to 62.5 μM with corresponding sensitivity of 0.003 μAμM-1. The proposed sensor is simple, easy and cost effective which will have a great potential in electrochemical biosensor
