Electrocatalytic oxidation of some amino acids on a cobalt hydroxide nanoparticles modified glassy carbon electrode

A Novel Non‐Enzymatic Glucose Sensor Based on Cobalt Nanoparticles Implantation‐Modified Indium Tin Oxide Electrode

“…The results above indicated that CoNPs/ITO electrode exhibit excellent electrocatalytic activity toward the oxidation of glucose. The proposed mechanism was consistent with the literatures 37, 57, 58, in which the glucose was oxidized by active Co(IV) species with cyclic mediation redox processes according to the following reactions:, …”

“…In this mechanism, Co(III) species is oxidized to Co(IV) and then Co(IV) species accordingly oxidizes the glucose followed by the regeneration of Co(III) species 57.…”

Electrochemical detection in vitro and electron transfer mechanism of testosterone using a modified electrode with a cobalt oxide film

“…In accordance with Tabeshnia et al [15], three oxidation processes are characteristic of different species of cobalt oxide electrodeposited on the GCE surface, but the electrochemical behavior of the modified electrode (Fig. 3) shows only one well-defined oxidation process at a formal potential (E 1/2 ) of 0.25 V (peaks 1 and 4), characteristic of the oxidation reaction of the Co 3 O 4 /CoO(OH) pair (Eq.…”

“…This would then be an indication that testosterone has been oxidized by the Co IV species formed. Several scientific papers have evoked this mechanism in order to explain this behavior in carbohydrate oxidation, hydrazine, paracetamol and acetylsalicylic acid [15][16][17].…”

Electrokinetic and Impedimetric Dynamics of FeCo-Nanoparticles on Glassy Carbon Electrode

“…The surface of a GCE can be modified in a number of ways in order to improve its performance in various electrochemical systems. Conducting polymers [9][10], carbon nanotubes [11], nanoparticles [12][13][14] have all been used to modify glassy carbon surfaces. In recent years, modification of solid electrodes with nanoparticles has attracted considerable interest.…”
