Abstract :Nanoparticles are nano-sized materials that can be widely used in fields such as medicine, pharmacology, and industry. The use of natural and easily available materials in nanoparticle synthesis is preferred because it is economical. Plants are extremely suitable for the synthesis of nanoparticles due to their natural and easy availability and the large number of components they contain with different properties. For this purpose, silver nanoparticles and zinc nanoparticles insert ignore into journalissuearticles values(AgNPs and ZnNPs);, two different nanoparticles were synthesized from an edible plant, watercress insert ignore into journalissuearticles values(Nasturtium officinale);. SEM insert ignore into journalissuearticles values(Scanning electron microscopy);, SEM-EDX insert ignore into journalissuearticles values(Scanning electron microscopy-Energy dispersive X-ray);, UV-VIS spectroscopy, XRD insert ignore into journalissuearticles values(X-ray crystallography);, and FTIR insert ignore into journalissuearticles values(Fourier Transform Infrared Spectrophotometer); analyses of these nanoparticles were performed. In addition, the antimicrobial effects of these synthesized nanoparticles were determined by the disk diffusion method. As a result, nanoparticles obtained from Nasturtium officinale were effective on gram-negative bacteria insert ignore into journalissuearticles values(Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa);, gram-positive bacteria insert ignore into journalissuearticles values(Staphylococcus aureus, Streptococcus pyogenes);, and fungi insert ignore into journalissuearticles values(Candida albicans);. In particular, AgNPs with broad-spectrum antimicrobial activity were obtained from the watercress. While ZnNPs showed inhibition effects of 49% on K. pneumoniae, 51% on S. aureus, and 62% on C. albicans, AgNPs showed inhibition effects of 93% on P. aeruginosa, 87% on S. aureus, 81% on E. coli, 80% on C. albicans, 72% on K. pneumoniae, and 56% on S. pyogenes. Thus, it has been shown that Nasturtium officinale can be used effectively in the production of new biotechnological products, especially with antimicrobial properties.
