| Abstract: | A uric acid (UA) biosensor based on uricase immobilized on ZnO nanowires was studied by quartz crystal microbalance (QCM). The stability of immobilized uriease was studied. Uficase was immo-bilized in PBS solution. And the frequency response showed a linear dependence on the uric acid concen-tration ranging from 5.0 × 10-6 to 8 × 10-5 molL-1. The results indicated one - dimensional ZnO structure is a good material for biosensor application. |
