The Study Of Poly [N (3 Ferrocene Acetamino Propyl Pyrrole] Film Modified Glucose Electrode, Chengyun Tian, Jing Chen, Li Zhang

Journal of Electrochemistry

A poly [N (3 ferrocene acetamino propyl pyrrole)]film modified electrode was fabricated and studied by cyclic voltammetric method. The result shows that the modified electrode can give stable redox peaks of ferrocene, and an obvious catalytic peak due to glucose; This modified electrode was used to tabricate a glucose sensor which operates at +0.2 V, so that the ascorbic acid or uric acid doesn't affect the accuracy detection of glucose concentration. The sensor has a linear range of 0.1～10 mmol/L glucose, which the period of long term stability and response time of the sensor are about ten days and 2 …
