Zinc Oxide:Gold Nanoparticles (zno:Au NPs) Exhibited Antifungal Efficacy Against Aspergillus Niger and Aspergillus Candidus

Fungal pathogens are a major health issue that threatens the era of antifungal drugs commonly used in the treatment of infections. An effective approach of biosynthetic nanoparticles can be used as antifungal agents owing to their intrinsic features such as their simplicity, non-toxic, and physicochemical properties. Therefore, this study was aimed to molecularly ascertain Aspergillus species known to cause aspergillosis and investigate the potency of zinc oxide:gold nanoparticles (ZnO:Au NPs) against the fungal pathogens. Two Aspergillus strains retrieved with potato dextrose agar (PDA) culture media from commercial food products in South Africa were molecularly identified using calmodulin (CaM) gene region. DNA sequence phylogeny of the gene showed that the strains were A. niger and A. candidus. ZnO:Au (1
