In recent decades, respiratory tract infection viruses, particularly SARS-CoV-2, have become a major global concern due to their rapid transmission and high mortality rates. Innovative antiviral coatings and textiles incorporating nanoparticles and other compounds have been explored in response. This study examined features, cytotoxicity, and the antiviral properties of three bioactive nano-silver-based compounds functionalised with organic paints, specifically for use in personal protective equipment like masks. We assessed onsite synthesised nanosilver alongside commercially available antibacterial additives, including nanosilver dispersed in colloidal silica and silver sodium hydrogen zirconium phosphate, as potential antiviral agents in organic paints against Human coronaviruses, which represent respiratory tract infection viruses. Developed organic paints have been assessed using STEM transmission electron microscopy and energy-dispersive X-ray spectroscopy. To evaluate the cytotoxicity and antiviral efficacy of these paints, we employed a neutral-red-uptake cytopathic assay, with data analysis conducted using smartphone technology. The results showed that nanosilver on colloidal silica functionalized on organic paint exhibited the most significant antiviral activity and non-cytotoxicity in comparison to other evaluated materials.
