%X The aim of this study is to synthesize silver nanoparticles (AgNPs) by green synthesis methods using pistachio (Pistacia vera L.) plant extract. Green synthesis is a biological method in which nanoparticles are easily obtained; as well as being environmentally friendly and inexpensive in terms of cost, and being more preferred than chemical and physical methods. AgNPs obtained by the reaction were chacarterized with UV visible spectrophotometer (UV-vis), fouriertransformed infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric and differential thermal analysis (TGA-DTA), scanning electron microscopy and energy dispersive X-ray device (SEM-EDX). Silver nanoparticles were found to have a maximum absorbance at 460.67 nm. FTIR analysis was performed to analyze the phytochemicals involved in the reduction of AgNPs. Using the Debye-Scherrer's equation, the crystal size of the synthesized nanoparticles was calculated as 16.7 nm. AgNPs spherical appearance were detected by transmission electron microscopy. The antimicrobial effect of synthesized AgNPs were tested on gram-positive and gram-negative bacteria, and by the minimum inhibitory concentration (MIC) method on fungi (yeast). As a result, it was determined that the synthesized silver nanoparticles had antimicrobial effect
