Synthesis of silver oxide nanoparticles using gomutra mediation and their investigations on anti-oxidant property

Abstract

Animal and plant waste which are readily available with no cost in the nature can be considered as the mediating materials for the synthesis of many metal/metal oxide nanoparticles. Rice husk, neem plant, cow urine etc., are few among them which can be considered as reducing agents for the synthesis of silica, and silver nanoparticles respectively. In this study, we present a straightforward green synthesis of silver nanoparticles that uses gomutra (Cow urine) as a reducing agent due to the presence of numerous biological components. The method was opted due to its biocompatibility and environment friendly nature. An X-ray diffraction measurement (XRD) was used to identify the phase of the as-synthesized silver oxide nanoparticles, and the face-centered cubic nature of the as-synthesized silver oxide nanoparticles was determined. The presence of silver oxide was shown by Fourier transform infrared spectroscopy (FTIR) on the nanoparticles, with a prominent peak at 520 cm−1. The spherical shape of the silver oxide nanoparticleswith a particle size estimated atabout 18 nm is supported by FESEM examinations, and energy dispersive x-ray analysis (EDAX) supports 37.99% of silver and 36.64% of oxygen in the nanoparticlessynthesised. The biological activities of the silver nanoparticles were investigated in addition to the aforementioned studies for their potential anti-oxidant property. The work also revealed a cost-effective industrial scale production of gomutra-mediated silver nanoparticles for a range of biomedical applications.
