A new nickel-based co-crystal complex electrocatalyst amplified by NiO dope Pt nanostructure hybrid; a highly sensitive approach for determination of cysteamine in the presence of serotonin

“…According to previous reports, inorganic complexes, especially complexes with nickel central atom can be used as a suitable electrocatalyst in the analysis of important pharmaceutical and biological constituents 47 – 52 . Although nanomaterials such as carbon nanotubes and graphene with high-conductivity have been proposed for the preparation of electrochemical sensors, their high cost, hard synthesis methods, and high capacitive charging current are some of the most important criteria for their use in electrochemical sensors 53 – 61 . Accordingly, the use of metal oxides has been used as a suitable alternative to this category of materials 62 – 66 .…”

Sensitive Electrochemical Detection of Caffeic Acid in Wine Based on Fluorine-Doped Graphene Oxide

“…As noble metals are expensive, carbon-based electrochemical sensors offer an inexpensive route toward the quantification of CA. Graphene and its derivatives are widely used in biological applications, electrochemical sensing, and energy storage due to their remarkable physicochemical properties [24,25,26,27,28,29,30,31,32,33,34,35,36]. Array-based sensing approaches (nose/tongue strategies) using graphene oxide have been reported for the detection of biomatrices and organic molecules [37,38,39].…”
