The manufacture of silver nanoparticles using plant extract is a simple, worthwhile, and ecologically friendly method. We present the use of in this study Crocus sativus .L petal extract is being used to create environmentally friendly nanoparticles. In the green approach, UV-Vis spectroscopy is utilised to characterise and confirm the presence of silver nanoparticles containing reduced silver ions. The XRD confirms the silver nanoparticles' crystalline structure formed in this process. Scanning electron microscopy reveals predominantly spherical and triangular shapes of the nanoparticles, with sizes ranging from 20 to 45 nm. To examine electrochemical properties, cyclic voltammetry and electrochemical impedance studies were utilised. Consequently, when subjected to the disc diffusion method, the synthesized silver nanoparticles exhibit enhanced antibacterial activity against various strains such as Pseudomonas aeruginosa, Proteus vulgaris, Enterococcus faecalis, Streptococcus Mutans, Enterococcus aeruginosa, and Bacillus subtilis.
