The successful development of multifunctional cotton fabrics with antimicrobial and antiviral activities is essential to prevent the proliferation of microorganisms and transmission of coronavirus virions today, especially with the emergence of new variants of SARS-CoV-2. In this work, we developed antimicrobial cotton fabrics with Ag/TiO 2 nanoparticles synthesized via sonochemistry. Here, we show that more than 50% of infectious SARS-CoV-2 remain active after prolonged direct contact self-disinfecting materials capable of inhibiting the proliferation of Escherichia coli and Staphylococcus aureus . The findings bring several epidemiologic worries about using silver and TiO 2 as self-disinfecting nanostructured agents to prevent coronavirus transmission.
