Abstract

This present work was studied the development of a molecularly imprinted polymer (MIP) based on the polyazo-Bismarck Y) for detection of uric acid. The film MIP was electrodeposited on the fluorine-doped tin-oxide (FTO) glass electrode surface by electropolymerization of Bismark Brown Y monomer in presence of uric acid as the template molecule. The MIP-poly(azo-Bismark Y) sensor displays a good electrochemical response, high sensitivity and selectivity in specific binding of the uric acid. Under the optimized experimental conditions, the voltammetric response of the proposed sensor was linear in the concentration range of 0.20 mmol L-1 to 0.60 mmol L-1, with detection limit of 0.17 mmol L−1.
