Patent ID: 7384659

Claim:
A method of producing a non-enzymatic whole blood uric acid detecting electrode strip comprising the steps of: (a) coating a conducting film on one side of an electrically insulating substrate to form an electrode system with an isolated and disconnected anode and cathode; (b) coating an electrically insulating film on a part of the anode and cathode of the electrode system, wherein one end of the anode uncovered with the conducting film forms at least a reference electrode and the other end forms an anode connector, and one end of the cathode uncovered with the conducting film forms at least a working electrode and the other end forms a cathode connector; and an exposed part of the electrode system not covered with the insulating film forms an electrochemical reaction zone for forming a reaction layer; and (c) adding dropwise a reaction film formulation onto the electrochemical reaction zone in step (b), and drying it to form the reaction layer; wherein the formulation comprise an electron mediator, a water-soluble polymer carrier and a volatile organic solvent agent.
