| Abstract | : | Development of uric acid sensor based on molecularly imprinted polymer (MIP) was studied. The sensor was developed by coating the imprinted polymethacrylic acid on the surface of a hanging mercury drop electrode (HMDE) at -1 V (vs. Ag/AgCl) during 60 s. Uric acid was accumulated on the modified electrode at -1 V (vs. Ag/AgCl) during 60 s in acetate buffer pH = 5 and stripped at scan rate of 59 mV/s. Oxidation of uric acid on the surface of modified electrode is irreversible through the diffusion controlled process and polymethacrylic acid is a non-electrical conducting polymer. The current signal obtained from the analysis of uric acid by using HMDE is higher than that of the HMD-polymethacrylic acid (polyMAA), HMD-MIP and HMD-non imprinted polymer (NIP) electrode. The HMD-MIP has demonstrated its performance as a sensitive voltammetric sensor for uric acid. The modified electrode has been tested for the determination of uric acid in the serum sample with recovery percentage of 95.7% (n = 2). The limit of detection obtained was 6.0 × 10-10 M |
