Ultra-fast Microwave-assisted Synthesis of Highly Narrow-sized and Pure Silver Nanoparticles with Enhanced Bactericidal Activity

In this research, highly pure Ag nanoparticles were prepared through a microwave-assisted precipitation method by which pure Ag NPs have been achieved in ۱۵ minutes. XRD analysis showed that all synthesized Ag NPs have a pure phase and FCC crystal structure. Additionally, FESEM was utilized to confirm the pseudo-spherical morphology of Ag NPs, with an average particle size distribution of ۷۶ nm. Furthermore, the prepared NPs were evaluated by HRTEM in which the results confirmed both SEM and XRD data. Finally, Ag NPs demonstrated superior antibacterial activity against E. coli and S. aureus compared to Gentamicin.
