ABSTRACT

Biogenically synthesized metal nanoparticles have attracted significant attention due to their diverse biomedical applications in the rapid advancement of nanotechnology. In the present study, gold nanoparticles were synthesized using an eco-friendly method, where Zingiber officinale (ginger) rhizome extract served as a natural reducing agent for Gold (III) chloride hydrate (HAuCl?). The resulting nanoparticles were thoroughly characterized using UV– Visible spectroscopy, FTIR, EDX, and SEM analyses. Their antifungal activity was evaluated against Aspergillus niger and Saccharomyces cerevisiae through the agar well diffusion method, which revealed distinct zones of inhibition, confirming the remarkable antimicrobial potential of the Zingiber officinale mediated gold nanoparticles (ZGNPs). Keywords : Gold nanoparticles, Zingiber officinale, SEM, UV-Visible, FTIR, Zone of inhibition
