This document discusses a study that investigated the antifungal and anti-mycelium activities of biogenic silver, copper, zinc oxide, and gold nanoparticles. The nanoparticles were tested against four fungal strains (Candida albicans, Cryptococcus neoformans, Aspergillus niger, Fusarium oxysporum). The minimum inhibitory concentrations of silver, copper, and zinc oxide nanoparticles were determined to be ≤8 μg/ml for the non-spore forming fungi and ≤16 μg/ml for the spore forming fungi. Anti-mycelium effects were observed for A. niger and F. oxysporum, with silver nanoparticles showing the highest effect at 72.8%. The
