Abstract
Bottom-up approach for the green synthesis of silver nanoparticles (AgNPs) from Allium sativum cloves using ultrasound-assisted technique has been investigated. The fabricated AgNPs were characterized using advanced techniques of spectroscopy, scattering, and microscopy. The synthesized AgNPs have a size distribution of 36.15 ± 8.54 nm, as confirmed by TEM analysis and 44.18 ± 0.55 nm as per XRD analysis. The fabricated AgNPs in this range exhibited greater surface plasmon resonance (SPR) for absorption, scattering and extinction coefficient. Higher negative ζ potential showed long term stability of fabricated AgNPs without agglomeration. Antimicrobial efficacy of fabricated AgNPs demonstrated high activity against pathogenic bacteria making them a promising candidate for applications in medical, environmental, biomedical, food packaging and allied fields.
