Non-enzymatic disposable uric acid detecting electrode strip, method for producing the same and its use

摘要

The present invention relates to a non-enzymatic disposable uric acid detecting electrode strip which directly detects the concentration of uric acid in liquid sample under a low operation voltage of below 400 mV and pH value from 7.0 to 10.0. When the electrode strip is applied to detect the concentration of uric acid in human body, it avoids interference signals caused from any other components in blood and will not be interfered by ascorbic acid unless the concentration of ascorbic acid increases to 15 times of its normal concentration in blood. Not only serum but also whole-blood can be taken as a sample for detecting the uric acid concentration thereof. The uric acid detecting electrode strip is modified by a water soluble redox electron mediator. The electrode strip is easy to carry and can be easily made, particularly mass-produced.
