Abstract

The present invention discloses a biosensor, a biostrip and a manufacture method of determination of uric acid by a non-enzymatic reagent, and particularly to the applications of determination of uric acid by a non-enzymatic reagent, which is useful for the quantification of the uric acid levels in the samples. The biosensor of the invention comprises at least a sensor, a biostrip and a non-enzymatic reagent for the determination of uric acid, wherein the biostrip has at least two working electrodes and at least one reaction zone and the non-enzymatic reagent for the determination of uric acid is disposed in the reaction zone on the biostrip, and has at least a tetrazolium salt and an active electron mediator, wherein the reaction zone is used for a sample to initiate the oxidation-reduction reaction of the tetrazolium salt and then, according to the oxidation-reduction reaction, with the active electron mediator and the two working electrodes, an electronic signal is transmitted to the sensor to produce a corresponding micro-current intensity which is in turn calculated by the sensor to reflect the uric acid level in the sample.
