A novel nanocomposite based on mycosynthesized bimetallic zinc-copperoxide nanoparticles, nanocellulose and chitosan: Characterization, antimicrobial and photocatalytic activities

Abstract

Background: 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 oxides nanoparticles, nanocellulose, and chitosan was ready through an ecofriendly method. Characterization, antimicrobial and photocatalytic activities were evaluated.

Results: The result revealed that the prepared nanocomposite exhibited antibacterial activity against Bacillus subtilis, Escherichia coli and Staphylococcus aureus, where MICs were 7.81, 31.25 and 62.5 µg mL⁻¹. As well, the nanocomposite showed potential antifungal activity against Aspergillus brasiliensis where MIC was 7.81 µg mL⁻¹, but had minimal antifungal efficacy against Cryptococcus neoformans and Candida albicans where the MIC was 250 µg mL⁻¹ for each other. Furthermore, the nanocomposite had photocatalytic activity. The bimetallic and nanocomposite materials were characterized via physiochemical and topographic analysis.

Conclusions: In conclusion, the prepared nanocomposite based on mycosynthesized bimetallic zinc-copper oxides nanoparticles nanocellulose and chitosan has antimicrobial and photocatalytic activities which can be applied to various environments.
