Abstract

In this study, silver nanoparticles (AgNPs) were synthesised using the Prunus cerasifera pissardii nigra (PC) leaf extract in an easy, low-cost and environmentally friendly way. According to the ultraviolet-visible (UV-vis) spectrophotometer analysis data, the nanocrystals demonstrated a characteristic peak at 456 nm. Scanning electron microscopy (SEM), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and energy-dispersive X-ray (EDX) spectroscopy analyses revealed that the morphological structures of the biosynthesised AgNPs were mostly spherical. According to the results of X-ray diffraction (XRD) analysis, it was determined that the crystal structures of AgNPs were cubic. The size of the nanoparticles was calculated as 23.60 nm using the Debye-Scherrer equation. The zeta potential of the synthesised nanomaterial was measured as -15.5 mV. The minimum inhibitory concentration (MIC) values of AgNPs on Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922, Bacillus subtilis ATCC 11774, Pseudomonas aeruginosa ATCC 27853 and Candida albicans ATCC 10231 were determined to be 0.062, 0.250, 0.125, 0.500 and 0.125 µg mL-1, respectively.
