Synthesis and characterization of multifunctional gold and silver nanoparticles using leaf extract of Naregamia alata and their applications to catalysis and control of mastitis

Abstract

Phytoreduced nanoparticles have multi functionalities because of their sustainable origin and biocompatible nature. We report the synthesis and characterization of silver and gold nanoparticles using leaf extract of the herb Naregamia alata. The non-classical source of energy, the microwave radiation from a domestic microwave oven performs the reduction of the metal ion precursors. The spherical silver nanoparticles have an average diameter of 18.05±4.73 nm and the poly shaped gold nanoparticles possesses an average size of 27.92±9.19 nm. The powder diffraction patterns witnessed the diffraction of X-rays from different crystal planes namely (111), (200), (220) and (311) planes of the fcc nanosilver and nanogold. The actions of the six major mastitis pathogens were inhibited by utilizing the antimicrobial power of the new silver and gold nanoparticles. The colored pollutants from paper, printing and textile industries like eosin Y and methyl red were degraded without irradiation of light using the catalytic power of the synthesized noble metal nanoparticles. The reduction of the organic compound, 4-nitrophenol by NaBH4 in the presence of nanocatalysts increases the laboratory value of the present study.
