“…Bimetallic nanoparticles have been used in the fabrication of nanosensors, nanochips, nano semiconductors and nanocoating. For example, Ag-Cu, Au-Cu, Fe-Mn, Pd-Ru, Ag-Cu, Co-Ni, Au-Ag, Au-Pt, Cu-Sn and Pd-Au bimetallic nanoparticles have been used to fabricate sensors/biosensors that can sense dimethoate [34], hydrazine [30] and detect Salmonella typhimurium in milk samples [275], as well as an anti-cancer drug [276], anti-inflammatory drug 4-aminoantipyrine [277], luteolin [278], favipiravir [279], diclofenac [280], glucose in serum [281] and coal mine gases sensor [131]. For detecting pesticide contaminants in the environment, many bimetallic nanoparticles have been used including Ag-Au, Au-Pd, Au-Pt, Au-Ag for detecting organophosphorus pesticides, carbamates nerve agents, and pesticides of leachate in contaminated groundwater [282][283][284][285].…”
