Effect of reducing agent concentrations and temperature on characteristics and antimicrobial activity of silver nanoparticles

In this study, the fabrication of colloidal silver nanoparticles (AgNPs) by cost-effective and environmental friendly method has been demonstrated. Rhodomyrtus tomentosa acetone extract (RAE) was used for the first as combined reducing and capping reagent time for AgNPs synthesis. The AgNPs were characterized by UV-visible spectroscopy, FTIR, XRD, zeta potential and DLS. AgNPs demonstrated profound antibacterial activity against Staphylococcus aureus with MIC and MBC ranging between 3.1-6.2 and 6.2-50 mg/ml, respectively. The outcomes of this study indicated that the synthesized AgNPs could be applied as an effective antimicrobial agent
