摘要：

Based on uricase-immobilized silk fibroin membranes and oxygen electrode, an amperometric biosensor for uric acid in flow-injection analysis has been developed. In the sensor, We first introduced a tailing inhibitor-ion pair reagent into a buffer system so as to eliminate all interference from hemacyte,macromolecules and small molecular weight charged species besides electroactive specie ascorbate in complex matrices.
