Electrodeposited copper nanoparticles for creatinine detection via the in situ formation of copper-creatinine complexes

Rapid electrodeposition of Cu nanoparticle film on Ni foam as an integrated 3D free-standing electrode for non-invasive and non-enzymatic creatinine sensing

“…For this reason, over the last decade, investigators have prepared multiple electrode materials, for example carbon nanomaterials, 13–16 molecularly imprinted polymers, 17,18 metal–organic frameworks, 19,20 and metal or metal oxide nanoparticles 21–25 to construct non-enzymatic creatinine electrochemical sensors. Among them, copper and copper oxides are often used as electrode materials for creatinine detection due to their excellent electrocatalytic activity and the strong complexing ability of copper ions with creatinine.…”

Electrochemical detection of creatinine: exploiting copper(ii) complexes at Pt microelectrode arrays

“…18 Recognizing the significance of addressing these shortcomings, recent developments have led to the creation of non-enzymatic creatinine sensors. 19–23 This work proposes an alternative methodology for the non-enzymatic detection of creatinine, an apparently electrochemically inert compound. Specifically, the detection mechanism relies on the formation of electrochemically active creatinine complexes and direct voltammetric analysis at microelectrode arrays.…”

Copper oxide nanoparticles fabricated by green chemistry using Tribulus terrestris seed natural extract-photocatalyst and green electrodes for energy storage device

“…For the production of copper oxide NPs, various techniques have been employed by different researchers for different purposes. These consist of wet electrodeposition 20 – 22 and chemical deposition 23 , 24 , chemical reduction techniques (hydrothermal) 19 – 22 , and others. These techniques require high pressure and temperature, and the majority employ hazardous chemicals that are harmful to people and the environment 25 , 26 .…”
