Ultrasensitive and highly selective sandpaper-supported copper framework for non-enzymatic glucose sensor

High rate fabrication of copper and copper–gold electrodes by laser-induced selective electroless plating for enzyme-free glucose sensing

“…We observed that during this period, all samples maintained $93-96% their initial electrocatalytic activity concerning non-enzymatic glucose sensing. Moreover, the sensor characteristics of copper and coppergold structures produced by SSAIL were compared with analogical enzyme-less electrodes known from the literature [47][48][49][50][51][52][53][54] (Table 3). Thus, one can conclude that SSAIL is a useful and efficient technique for the fabrication of materials suitable enzyme-free sensing of biologically important analytes.…”

A Highly Sensitive Electrochemical Glucose Sensor Based on Room Temperature Exfoliated Graphite-Derived Film Decorated with Dendritic Copper

“…Figure S2 shows that Cu can be oxidized to Cu (I), Cu (II), and Cu (III) in alkaline environment. The widely accepted catalytic mechanism of copper for glucose is that Cu (III) is a strong oxidant and the glucose can be oxidized into gluconate [ 30 ].…”

A comparative electrochemical study of non-enzymatic glucose, ascorbic acid, and albumin detection by using a ternary mesoporous metal oxide (ZrO2, SiO2and In2O3) modified graphene composite based biosensor

“…Accordingly, a difference in the oxidation state of glucose molecules adsorbed onto the metal surface leads to a difference in the metal-glucose complex, lowering the quality of the glucose-metal bond and in turn lowering the desorption rate of glucose molecules. [6][7][8] The impersonating cycle of metals and metal oxides, such as Au, Cu, Pt, Ni etc., [9][10][11][12][13][14][15][16][17][18] have been accounted by the direct electrochemical oxidation of glucose and electron move. Among these metals, ZrO 2 based substrates have been considered as the best because of their ease of production, high strength, and excellent synergistic properties.…”
