Ascorbic Acid Sensor

By fixing Quantum Dots (QDs) on gold electrodes with dithiol compounds, a novel Ascorbic Acid sensor without any redox mediator was desighed. First, the fabrication process of sensor was described.Sencond, the characteristics of the sensor were investigated. Third,the sensor was tested in Ascorbic Acid solutions of different concentrations.From the results,it shows that the performance of photoelectrochemical sensor were influenced by the bias voltage and the amplitude of photocurrent changed with the Ascorbic Acid concentration linearly in detection range.

Ascorbic Acid Sensor

A new ascorbic acid electrochemical sensor was made by electrostatic assembly of ferrocene polymer monolayer on the surface of gold electrode which modified with negatively charged alkanethiol. Cyclic voltammetry and current-time curve were employed to investigate the electrochemical characteristics of the sensor. The ferrocene monolayer modified electrode exhibit excellent electrocatalytic response to the oxidation of ascorbic acid. The anodic overpotential was reduced by about 180 mV compared with that obtained at a bare gold electrode in cyclic voltammetry. Under the optimal conditions, the linear range of the sensor response to ascorbic acid was from 0.05 to 1 mM and the detection limit was 2.710-5 M. The sensor possesses simple preparation, fast response and good electrochemical stability.
