Economic fast synthesis of olive leaf extract and silver nanoparticles and biomedical applications

In this study, silver nanoparticles (AgNPs) were synthesized economically and simply using an environmentally friendly method with the extract obtained from agricultural waste olive leaves. AgNPs synthesized according to the analysis data were determined to have maximum absorbance at 433.5 nm wavelength, spherical appearance, 7.2 nm crystal nano size and -19.9 mV zeta potential. It was determined by the microdilution method with Minimum Inhibition Concentration (MIC) that AgNPs exert a suppressive effect on the growth of pathogen gram-negative, positive bacteria and yeast at very low concentrations. The cytotoxic effects of the particles were investigated on healthy cell lines (HDF) and cancerous cell lines (U118, CaCo-2, Skov-3). AgNPs showed up to 70% suppression in cancer cell lines.

Automated summary

In this study, silver nanoparticles were synthesized using extract obtained from agricultural waste olive leaves, showing suppressive effects on the growth of pathogen gram-negative, positive bacteria and yeast at low concentrations. Additionally, the nanoparticles exhibited up to 70% suppression in cancer cell lines, indicating their potential as a promising anticancer agent.
