Rapid Colorimetric Detection of Hg (II) Based on Hg (II)-Induced Suppressed Enzyme-Like Reduction of 4-Nitrophenol by Au@ZnO/Fe3O4 in a Cosmetic Skin Product
Herein, we synthesized gold-coated ZnO/Fe3O4 nanocomposites. Initially, we prepared Fe3O4 magnetic nanoparticles based on the co-precipitation of Fe3+ and Fe2+ under aqueous ammonia as a precipitating agent. Thereafter, the ZnO/Fe3O4 composite was prepared by dispersing the synthesized magnetic nano...
