Metal nanoshells consists of a dielectric core surrounded by a thin noble metal shell, possess unique optical properties, which render nanoshells attractive for use in different technologies. This paper reports a facile method for growth of small gold nanoparticles on the functionalized surface of larger silica nanoparticles. Mono-dispersed silica particles and gold nanoparticles were prepared […]
The advantage of using plants and plant metabolites over expansive and toxic chemical methods for nanoparticles (NPs) synthesis has fascinated researchers to investigate the mechanisms of bio-reduction of metal ion for various biomedical applications. Herein, pineapple leaf extract was used for the synthesis of silver (Ag) and bimetallic silver-gold (Ag-Au) core-shell NPs which offered an […]
