In Situ Electrodeposited Gold Nanoparticles on Polyaniline-Modified Electrode Surface for the Detection of Dopamine in Presence of Ascorbic Acid and Uric Acid

Zwitterionic oligomers of 3-aminobenzoic acid on screen-printed electrodes: structure, properties and forensic application

“…Mahalakshmi and Sridevi prepared a composite of polyaniline (PANI) with Au nanoparticles (AuNPs) on a glassy carbon electrode and so improved its selectivity for DA, applying electrocatalysis simultaneously with the π-π interactions. 27 This paper shows the use of electrochemically oxidized 3-aminobenzoic acid (3ABA) deposited on graphite screenprinted electrodes for recognizing NPSs, including aminoindane and SCs with primary, secondary, and tertiary amino groups (Fig. 1).…”

Melamine-derived N-rich C-entrapped Au nanoparticles for sensitive and selective monitoring of dopamine in blood samples

“…18 Recently, Mahalakshmi et al used an electrodeposition strategy to design a AuNP-coated polyaniline-modied glassy carbon electrode for the selective monitoring of DA. 19 Furthermore, a three-layer composite of AuNPs, choline, and graphene quantum dot-based carbon ber microelectrodes has been developed for the highly sensitive monitoring of DA without interference from AA. 20 Even though most of these exhibit excellent selective features, fabrication of low-cost and easy-to-handle sensing probes with exceptional sensitivity, selectivity, and reproducibility remains a big challenge for developing a portable electrochemical sensor for real-time applicability.…”

Screen-Printed Electrode Surface Modification with NiCo2O4/RGO Nanocomposite for Hydroxylamine Detection

“…Chemically modified electrodes improve mass transfer kinetics at low overpotential resulting in a decrease the interferences' effect and avoiding surface fouling [20][21][22][23][24][25][26]. The performance of the sensors has been improved due to significant advances in nanomaterials, for example in terms of sensitivity and a wide range of detection of target molecules [27][28][29][30][31][32][33][34][35].…”
