Electrochemical Analysis of Methanol with Nafion-Coated Copper Oxide Nanoparticles.

This work introduces a Nafion-coated copper(I) oxide nanoparticle electrode (Nafion/CuO/GC) designed for the electrochemical detection of methanol (CHOH). The responses of the composite material toward CHOH were enhanced by the selective permeation of CHOH through the hydrophilic channels of the Nafion membrane in combination with the electroactivity of CuO nanoparticles. The sensor displayed a linear detection range of 0.

Copper(II) phthalocyanine as an electrocatalytic electrode for cathodic detection of urinary tryptophan.

Herein, we introduce a novel method for tryptophan detection a reduction reaction facilitated by its interaction with a copper(II) phthalocyanine (CuPc) electrocatalytic electrode. This method addresses challenges associated with the susceptibility of the oxidation response to interference from various species when measuring tryptophan in bodily fluids. The reduction currents exhibit a linear increase with tryptophan concentrations in two ranges: 0.

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

This work develops a rapid and highly sensitive electrochemical sensor for creatinine detection at platinum microelectrode arrays (Pt-MEA). Copper(ii) ions are introduced to form the electroactive creatinine complex, which is then detected at Pt-MEA through a direct reduction reaction. Electrochemical behaviors of the creatinine complex are also explored at Pt macrodisc and microdisc electrodes in comparison with Pt-MEA.

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

Creatinine is an important biomarker of kidney diseases. In this work, a fast and facile electrochemical sensor was developed for creatinine detection based on the use of copper nanoparticle-modified screen-printed electrodes. The copper electrodes were prepared by simple electrodeposition of Cu (aq).

Microporous carbon for fast and simple electrochemical detection of imidacloprid insecticide in fruit and water samples.

Herein, a fast and sensitive electrochemical sensor was developed for imidacloprid detection using low-cost disposable microporous carbon screen-printed electrodes. The electrochemical behaviour of imidacloprid at the microporous material was investigated in detail. The developed sensor allowed imidacloprid detection in the linear range of 0.
