Electrochemical nonenzymatic glucose sensors catalyzed by Au nanoclusters on metallic nanotube arrays and polypyrrole nanowires

Protector-free, non-plasmonic silver quantum clusters by femtosecond pulse laser irradiation: in situ binding on nanocellulose filaments for improved catalytic activity and cycling performance

“…21 Au clusters have been generated through the process of the reduction reaction of tetrachloroaurate ions by e aq − . 22 They emit fluorescence, which is characteristic of quantum clusters, and nanoparticles larger than 5 nm exhibit both quantum and plasmonic properties, 22,23 where Pt particles are always small (<2 nm) and show neither quantum nor plasmon character. Thus, the characteristics of atomic clusters depend on the metal species, as defined by the given precursors.…”
