Lately, the green biosynthesis method has been more concerned with the use of waste vegetable and fruit shells, being less toxic, environmentally friendly, easy to synthesize and important in the manufacture of nanomedicines. The aim was to synthesize silver nanoparticles (AgNPs) from red Pumpkin peel hot aqueous extract and the ethanol extract in an environmentally friendly manner, replacing existing methods for synthesizing AgNPs using hazardous chemicals and toxic solvents. This research describes a green process whereby AgNPs were manufactured using silver nitrate and peel of red Pumpkin extract (hot aqueous extract and ethanol extract) as a reducing agent and coating. The nanoparticles were symbolized using UV-Vis, showed absorbance at 430 nm for both extracts consistent with AgNPs spherical particles within (350-550) nm wavelength spectrum and Scanning Electron Microscope (SEM) showed an average AgNPs diameter 67 nm and 56 nm respectively for the hot aqueous and ethanol extract.The current study effort investigates the findings Silver Nitrate concentration 1Mm for hot aqueous extract and ethanol extract. Silver nanoparticles were distinguished by Energy Dispersive X-Ray Spectroscopy (EDX) and Dynamic Light Scattering (DLS).
