Abstract

Nanobiotechnology has rapidly become a critical facet of nanotechnology. The green synthesis of silver nanoparticles, making use of the hull of black gram (Vigna mungo), paves the way for a simple and eco-friendly utilization of a domestic waste to a product with antioxidant and anticoagulant activities. The emergence of silver nanoparticles was characterized by a variety of methods UV–visible spectrophotometry, scanning electron microscopy added to energy dispersive spectroscopy, X-ray diffractometry, particle size distribution and FT-IR spectroscopy analyses. A discrete band at 421 nm was obtained from UV–visible spectroscopy of the silver nanoparticle suspension. The extract sourced from the hull of black gram showed evidence of the presence of a variety of functional moieties of phytochemicals using FTIR spectroscopy. These were also deemed responsible for maintaining the stability of silver nanoparticles. SEM and EDAX techniques combined, proved that the zero-valent silver nanoparticles were lesser than 100 nm in size. The crystallinity of the nanoparticles was confirmed, as deduced by the (1 1 1) plane, from XRD analysis. The potential of the phytochemicals in maintaining the steadiness of nanoparticles was implied by the zeta potential value that stood at −30.3 mV. In the current study, we have endeavored to comprehend the antioxidant and anticoagulant nature of the green-synthesized benign silver nanoparticles.
