Enzyme-free glucose sensor based on a three-dimensional gold film electrode

Glucose Oxidation on Gold-modified Copper Electrode

“…However, in the case of the sputter deposited Au film, no such peaks related to Cu were observed and several peaks relevant to Au appeared. 22 A broad peak starting at −0.4 V was representing the formation of AuOH followed by further oxidation to form AuO. The generated oxidized species of Au were sequentially reduced back to AuOH and Au at 0.0 V and −0.25 V, respectively, during the backward scan.…”

“…[10][11][12][13][14][15][16][17][18][19][20][21][22] In more detail, several single metal catalysts using Au, 10,12,[14][15][16]19,22 Pt, 10,12,16,18 Cu 10,20 and Ni 10,11,21 have been reported to have significant activities toward glucose oxidation. Particularly, Pt is a well-known catalyst for proton exchange membrane fuel cells and direct methanol fuel cells as both anode and cathode catalysts.…”

Templated Synthesis for Nanoarchitectured Porous Materials

“…Ordered macroporous architectures derived from inverse opal components also show great potential in sensors, 264 and catalyst supports, 265 owing to their high surface area, large pore volume and unique optical properties. In addition, because of their well-arranged structure, these materials can selectively guide the penetrating direction of light due to the trapping of photons with a specific wavelength.…”

Facile wet-chemical synthesis of differently shaped cuprous oxide particles and a thin film: Effect of catalyst morphology on the glucose sensing performance

“…Consequently, the demand for the development of new and suitable non-enzymatic electrocatalytic active electrodes has arisen in recent decades. New laboratory research on the topic involves the use of noble metals such as gold (Au) [3], platinum (Pt) [4], and alloys thereof [5,6]. However, these electrodes occasionally suffer from low selectivities, high costs and poisoning.…”
