Aim: The aim of this study is the synthesis of nanosilver particles (AgNPs) from Pelargonium quercetorum Agnew. (Geraniaceae) and evaluation of the antimicrobial and the cytotoxic potential of AgNPs. Methods: The synthesized AgNPs were evaluated for antimicrobial and anticancer efficacy using the minimum inhibition concentration method and MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium bromide) assay. Results: The AgNPs inhibited approximately 90% the growth of gram-positive Staphylococcus aureus and gram-negative Esherichia coli and yeast Candida albicans pathogens at a concentration of 500 μg/mL. The synthesized AgNPs showed excellent toxicity in MCF-7 cells, and specifically, pq70 AgNP inhibited the growth of MCF-7 cells by 52% at a concentration of 3.125 μg/mL. Conclusion: It was determined that the AgNPs, which had been synthesized from extracts that contained a high phenolic composition, were smaller in size, and showed high anticancer and antimicrobial properties.
