We carried out a systematic experimental and theoretical study on ZnS and ZnO as promising antimicrobial coatings for mitigation of the SARS-CoV-2 infection. The photodegradation of a methylene blue (MB) dye was evaluated for ZnO and ZnS coating cotton fabrics prepared by the hydro(solvo)thermal method. For understanding at the molecular level, the broad-spectrum biological activities of these materials were evaluated theoretical calculations. The biological targets used in this computational study were Fusarium Oxysporum fungi, E. Coli bacteria, and SARS-CoV-2 virus and their variants. The results suggest that both ZnS and ZnO can be used as a light-activated antimicrobial coatings on a large scale for the production of more efficient protection masks for SARS-CoV-2 infection mitigation.
