Abstract: A simple dopingcoating technique is described for immobilizing uricase using polyaniline and polystyrene and paraffin.The polyaniline uricase electrode with polystyrene coating has a fast response time (about 30 s at 0.35 V vs.SCE).The optimum pH and the dependence on potential are similar to those of polyaniline uricase electrode,the activation energy and stability of the polyaniline uricase electrode with polystyrene coating are 19.9 kJ•mol-1 and over 180 days,respectively.

Key words: Doping-coating method, Polystyrene, Bioelectrochemistry, Polyaniline,  Uricase
