Abstract:
A non-enzymatic disposable uric acid detecting electrode strip which comprises:an electric insulating substrate;a conducting film coated on one side of the substrate to form isolated and disconnected an anode and a cathode;an electric insulating film coated on a part of the conducting film, wherein one end of an uncovered anode of the conducting film forms at least a reference electrode and the other end an anode connector, and one end of an uncovered cathode of the conducting film forms at least a working electrode and the other end a cathode connector; anda reaction film comprising a carrier and a conductive mediator and being screen printed on a region containing at least the working electrode and the reference electrode so as to connect the working electrode and the reference electrode individually, wherein the carrier comprises a microcrystalline cellulose, a polymer and a buffer solution; and the conductive mediator comprises an electrolyte with a lower redox potential than that of uric acid; wherein said reaction film does not contain an enzyme.
