Abstract
Nanoparticles are used in many areas due to their superior properties. Recently, producing these particles using environmentally friendly synthesis methods has become very popular. Within this context, in this study, gold nanoparticles (AuNPs) were synthesized by using a quick, eco-friendly method with the green leaf extract of Artemisia absinthium (wormwood). The grain size of the AuNPs was determined as 13.40 nm according to the Debye-Scherrer equation. The inhibitory effects of the AuNPs on the growth of the tested microorganisms were determined by the minimum inhibitory concentration (MIC) method. The MIC is described as the minimum concentration of an antimicrobial agent that inhibits the growth of a microorganism. The obtained AuNPs were showed inhibitory effects on S. aureus, S. pyogenes, E. coli, P. aeruginosa strains and C. albicans yeast at concentrations of 0.250, 0.125, 0.125, 0.033 and 0.66 mg mL-1 respectively.
