The present study intended to synthesize, characterize silver nanoparticles (AgNPs) using Cosmos sulphureus (Cs) aqueous leaf extract and their antimicrobial and antioxidant activities. The UV-vis spectrophotometer exhibited an absorbance peak around 430-440 nm with color intensity from yellow to reddish brown after 4 days. SEM and EDX analysis showed AgNPs were pure and polydispersed and the size were ranging from 55 to 80 nm. XRD revealed that the nanoparticles were cubic and face centered in… Expand
