Research of Electrochemistry Measuring System Based on Saliva Glucose

Abstract:

According to the relationship of glucose content in diabetes saliva and blood, the biosensor for detecting saliva glucose was introduced based on electrochemical detecting principle, glucose oxidase was immobilized onto the surface of electrode by glutaraldehyde cross-linking. The measuring system was designed by using potentiostat for amperometric chemical sensors. The characters of the microsystem has been demonstrated with the detection of standard glucose solution concentration of saliva parameter. Compared with the data obtained from the instrument CHI660A, it showed that has a good linear relation in the linear range of 0-2200µmol/L, with the correlation coefficient of 0.9531.
