“…[6][7]12] However, even the state-ofthe-art technology for glucose sensing with Pt electrodes is not free from poisoning by adsorbed intermediates, [13] resulting in poor selectivity for direct glucose detection. It was reported for the first time in 1985 [3] that the electrooxidation of glucose is strongly subject to poisoning by adsorbed intermediates, which can be subsequently oxidized by electrochemical formed surface OH species at higher potentials. The kinetically controlled electrooxidation of glucose on a smooth platinum electrode has low sensitivity and poor selectivity.…”

“…The most serious problem of such sensors is their lack of stability due to the intrinsic stability of enzymes. [3][4][5][6][7] Therefore, numerous studies have been performed to overcome or alleviate the drawbacks of enzymatic glucose sensors. [8][9][10][11] Amperometric measurements allow observation of the electrochemical oxidation of glucose on a bare platinum (Pt) surface.…”

A three-dimensionally ordered, macroporous, inverse-opal platinum film was synthesized electrochemically by the inverted colloidal-crystal template technique. The inverse-opal film that contains platinum nanoparticles showed improved electrocatalytic activity toward glucose oxidation with respect to the directly deposited platinum; this improvement is due to the interconnected porous structure and the greatly enhanced effective surface area. In addition, the inverse-opal Pt-film electrode responds more sensitively to glucose than to common interfering species of ascorbic acid, uric acid, and p-acetamidophenol due to their different electrochemical reaction mechanisms. Results showed that the ordered macroporous materials with enhanced selectivity and sensitivity are promising for fabrication of nonenzymatic glucose biosensors.

“…(1) and (2), is assumed to be a rate-determining step. 22,23,26 Further, another oxidation wave, which has been reported to have the same character as the oxidation wave I, 22,23 could not be observed in the negativegoing sweep in the potential region where oxidation wave I appeared. We expected that the oxidation wave should be observed at the activated electrode, since sufficient time for the adsorption of glucose would have passed during the negativegoing sweep.…”

Activation Effects of a Platinum Electrode by Laser Pulse Irradiation on the Electro-Oxidation of Glucose in Alkaline Solution

et al. 2004

In order to demonstrate the activation effects of a Pt electrode by laser pulse irradiation, the electro-oxidation of glucose was tested at an activated Pt electrode by cyclic voltammetry. A fixed potential was applied to the electrode, and then the electrode was irradiated with laser pulses from a Nd:YAG laser at 20 Hz for 20 s. Activation by the laser pulse irradiation gave two remarkable effects on cyclic voltammograms from the electro-oxidation of glucose in a 0.1 mol dm -3 NaOH solution, i.e., surface modulation and cleaning effects. Significant differences were found in the cyclic voltammograms at the activated and at the simply polished electrodes. Such differences in the oxidation waves are attributed to a crystallographic change of the electrode surface induced by a laser ablation, accompanied by laser pulse irradiation. Due to the cleaning effect, the activated Pt electrode gave a sharp oxidation wave at -0.3 V even in real samples containing various organic compounds that could foul the electrode, though the activated Pt electrode lacked selectivity to the electro-oxidation of glucose.

Carbohydrates are detected by constant potential amperometric detection at a modi®ed electrode consisting of poly-1-naphthylamine coated glassy carbon with copper ions incorporated into the polymeric matrix. The polymer is electrodeposited onto the glassy carbon surface by cyclic voltammetric experiments, and copper ions incorporated by immersion of the modi®ed electrode in a 0.10 M cupric ions solution. The amount of copper incorporated into the polymeric matrix is regulated by controlling the immersion time. Cyclic voltammetric experiments showed that glucose was oxidized at the modi®ed electrode surface. The catalytic current for glucose oxidation was dependent on the amount of copper incorporated. Flow injection experiments allowed the determination of the working electrode potential at which maximum signal-to-noise ratios were obtained. The electrode was successfully used in the high performance liquid chromatographic analysis of various carbohydrates.
