Anodic stripping electrochemical analysis of metal nanoparticles

Electrooxidation, Size Stability, and Electrocatalytic Activity of 0.9 nm Diameter Gold Nanoclusters Coated with a Weak Stabilizer

“…[16] The same Au NCs converted to 4-10 nm diameter Au NPs after one electrochemical surface oxidationreduction cycle in acid, 2 min of ozone treatment, and after holding the potential at 0.30 V versus Ag/AgCl (3 M KCl) for various times in acidic KBr solution. We monitored the stability using our previouslydeveloped size [8,[36][37] and aggregation analysis [38] by anodic stripping voltammetry (ASV) and electrochemical SA/V measurements. [39] We previously used ASV to determine the composition and atomic arrangement of Cu/Au bimetallic nanostructures as well.…”

Characterization of SERS platforms designed by electrophoretic deposition on CVD graphene and ITO/glass

“…The sizedependent properties were monitored by linear scan voltammetry (LSV) that exhibited oxidation peaks at different potentials for Ag 13,14 and Au [15][16][17][18] NSs during anodic stripping. 19 This comes from the seminal work of Ivanova et al, 13 who experimentally corroborated what Plieth thermodynamically calculated 20 regarding the dependence of cluster size on the oxidation potential. Besides the size of NSs, shifts in peak potential have been demonstrated for the same NPs placed on different types of substrates, 21 different NP compositions in core-shell configurations, 22 NP agglomeration, 23 functionalized electrodes, 14 and different deposition methods.…”

Gold, Silver, and Palladium Nanoparticles: A Chemical Tool for Biomedical Applications

“…Further, the significant magnetic, transparent and electronic properties of AgNPs can be applied to control the microbial activities (Murphy et al, 2015). Another noble metal is palladium (Pd) that has extraordinary catalytic, and electronic features (Chaloupka et al, 2010;Pattadar et al, 2019). Palladium (Pd)NPs structures have been extensively used in applications such as the electrical equipment composition, as a sensor for exposure to several bio-analytes.…”
