Construction and application of an amperometric uric acid biosensor based on covalent immobilization of uricase on iron oxide nanoparticles/chitosan-g-polyaniline composite film electrodeposited on Pt electrode

Commercial uricase was immobilized covalently onto iron oxide nanoparticles/chitosangraft-polyaniline (Fe3O4-NPs/CHIT-g-PANI) composite film electrodeposited on surface of Pt electrode. Transmission electron microscopy (TEM) was used for characterization of Fe3O4-NPs. A uric acid biosensor was fabri...
