Synthesis of silver nanoparticles employing Bryophyllum pinnatum leaf extract and it's efficiency towards photocatalytic and antibacterial properties

Abstract

Silver nanoparticles (Ag NPs) were created in the current study using the Green Synthesis method from an AgNO3 solution and an extract of Bryophyllum pinnatum. Various techniques were used to precisely characterize the silver nanoparticles. UV–Vis spectroscopy was used to confirm the formation of Ag NPs. The crystallinity of the silver nanoparticles was revealed by the X-ray Diffraction (XRD). The average size of the silver nanoparticles was determined by dynamic light scattering analysis to be 65 nm. Antibacterial activity with minimum inhibitory concentration (MIC) against S. aureus (12 mm) and B. subtilis (12 mm) bacteria, both of which are gram positive, were effectively eradicated by Ag NPs. The Methylene blue (MB) dye was successfully broken down by the biosynthesized silver nanoparticles when exposed to natural sunlight and was tested at various exposure periods. The findings suggest that synthetic Ag NPs from B.pinnatum may be employed in the near future in the environmental and medical domains.
