A new glucose sensor has been reported and applied to the determination of glucose in urine. The measurment method is baed onthe sedimentation of silver by the reaction of glucose with the Tollens reagent. The amount of glucose was determined as the resonantfrequency chang of the quartz crystal because of the mass chang on the surface of piezoelectric sensor dure to the silver.A satisfactory correlation was observed between the glucose concentration and frequency chang at the range from 1. 0 X 10-6 t0 1. 0X 10-2 mol/L, and coefficient of variat...
