Abstract
Recently, nanomaterials have received much attention due to their important role in solving medical and environmental problems. In the present study, a novel nanocomposite based on mycosynthesized bimetallic zinc-copper oxide nanoparticles, nanocellulose, and chitosan being ready through an ecofriendly method. Characterization, antimicrobial and photocatalytic activities were evaluated. The result revealed that, the prepared nanocomposite gave antibacterial activity against Bacillus subtilis, Escherichia coli and Staphylococcus aureus, where MICs were 7.81, 31.25 and 62.5 µg/ml. As well, the nanocomposite showed potential antifungal activity against Aspergillus brasiliensis where MIC was 7.81 µg/ml, but had minimal antifungal efficacy against Cryptococcus neoformans and Candida albicans where the MIC was 250 µg/ml for each other. Furthermore, the nanocomposite had photocatalytic activity. The bimetallic and nanocomposite materials were characterized via physiochemical and topographic analysis. In conclusion, the prepared nanocomposite based on mycosynthesized bimetallic zinc-copper oxide nanoparticles nanocellulose, and chitosan has antimicrobial and photocatalytic activities which can be applied to various environments.
