Cu nanoparticles incorporated polypyrrole modified GCE for sensitive simultaneous determination of dopamine and uric acid

Graphene Oxide‐Templated Polyaniline Microsheets toward Simultaneous Electrochemical Determination of AA/DA/UA

“…However, electrochemical determination of these species based on anodic oxidation suffers from oxidation peaks overlapping at solid electrodes [2,3]. Till now, various modified electrodes have been attempted to solve the problems encountered in simultaneous determination of AA, DA and UA, for example, PDDA modified graphite electrode [4], amorphous silica gel modified carbon paste electrode [5], carbon-nanofiber modified carbon paste electrode [6], poly(acrylic acid)-multiwalled carbon-nanotubes composite-coated glassy-carbon disk electrode [7] and natural antibiotic lasalocid A cast glassy carbon electrode [8], etc.…”

Simultaneous Determination of Ascorbic Acid, Dopamine and Uric Acid at Pt Nanoparticles Decorated Multiwall Carbon Nanotubes Modified GCE

“…Very recently, we reported the electrochemical preparation of Cu nanoparticles incorporated polypyrrole modified GCE and its applications to the sensitive and selective simultaneous determination of DA and UA [30].…”

Electroanalytical Sensor Technology

“…Recent research highlights the interest in simultaneously quantifying physiologically relevant compounds such as uric acid, ascorbic acid and/or catecholamines [165][166][167]. A large body of literature describes the production of a variety of sensors with multi-analyte sensing capabilities, exploiting a variety of nanomaterials including CNTs [168][169][170], individual nanoparticles [171] and polymer nanocomposites [172,173] The electronic nose or tongue is an analytical instrument comprising an array of chemical sensors with partial specificity or cross-sensitivity to different components of a mixture/compound, and an appropriate method of pattern recognition and/or multivariate calibration for the data processing. They can quantitatively differentiate between the composition of complex liquids/gases.…”
