Synthesis and Characterization of Veronica Beccabunga Green Synthesized Silver Nanoparticles for the Antioxidant and Antimicrobial Activity

Abstract

The use of nano-agents in the healthcare field is an important alternative in reducing the increasing pathogenresistance. One of the main purposes of the nano mechanism is that the secondary metabolites produced naturally in plantsbecome more effective through metals. Silver (Ag) nanoparticles were obtained by green synthesis using Veronica beccabungaplant extract and AgNO3 in our study. Scanning electron microscopy was used for SEM, SEM / EDX images of synthesizedsilver nanoparticles. The interaction of V. beccabunga with Ag was explained by X-ray diffraction (XRD) analysis. Thecharacterization process was performed using an ultraviolet-visible (UV-vis) spectrophotometer and Fourier convertedinfrared spectroscopy (FT-IR). It was determined that silver nanostructures have an important antioxidant potential as a resultof 2,2-difenil-1-pikrilhidrazil (DPPH) analysis. The antimicrobial activity of synthesized metal nanoparticles was investigated,against some pathogens causing disease in humans, by the disk diffusion method. Ag NPs /Vb has been found to haveantibacterial effects against Bacillus subtilis ATCC 6633, Escherichia coli ATCC 25952, Pseudomonas aeruginosa ATCC27853 microorganisms. In our current study, Ag NPs / Vb appears to provide a remarkable effect for its use in medicine,pharmacology
