Green synthesis of multi-metallic nanocubes

Abstract

A facile synthetic route and growth mechanism of heterobimetallic cubical nanoparticles Au@AgCl and Ag@AgCl@Au have been developed using Muntingia calabura flower extract. The formation of nanoparticles has been confirmed through UV-Vis, powder X-ray diffraction and electron microscopy. The elemental composition of the nanoparticles has been evidenced by EDS analysis. Combing the UV-Vis spectral analysis and powder X-ray diffraction studies, the composition of bimetallic nanoparticles are assigned as Au@AgClNP and Ag@AgCl@AuNP. The prepared nanoparticles display good antibacterial activity which is comparable to standard kanamycin and ampicillin. � 2017 The Royal Society of Chemistry.
