The whole world is struggling with current coronavirus pandemic that shows urgent need to develop novel technologies, medical innovations or innovative materials for controlling SARS-CoV-2 infection. mode of infection still not well known and seems spread through surface, air, water. Therefore, the surrounding environment needs be disinfected continuous function. For purpose, excellent antiviral properties, cost effective, environmental friendly practically applicable should researched. Titanium dioxide (TiO2) under ultraviolet light produces strong oxidative effect utilized as photocatalytic disinfectant in biomedical field. TiO2 based photocatalysts are effective antimicrobial/antiviral agents ambient conditions potential used even indoor inactivation bacteria/viruses. Interestingly, recent studies highlight disinfection using photocatalysts. Here, scope emerging against has been discussed view their antibacterial activities various bacteria viruses (e.g. H1N1, MNV, HSV, NDV, HCoV etc.). state development nano-photocatalysts combat viral promising any other such variants viruses, future studies.

The emergence of a pandemic affecting the respiratory system can result in significant demand for face masks. This includes use cloth masks by large sections public, as be seen during current global spread COVID-19. However, there is limited knowledge available on performance various commonly fabrics used Importantly, need to evaluate filtration efficiencies function aerosol particulate sizes 10 nm μm range, which particularly relevant virus transmission. We have carried out these studies several common including cotton, silk, chiffon, flannel, synthetics, and their combinations. Although when single layer was ranged from 5 80% 95% particle <300 >300 nm, respectively, improved multiple layers were using specific combination different fabrics. Filtration hybrids (such cotton-silk, cotton-chiffon, cotton-flannel) >80% (for particles nm) >90% nm). speculate that enhanced likely due combined effect mechanical electrostatic-based filtration. Cotton, most widely material performs better at higher weave densities (i.e., thread count) make difference efficiencies. Our also imply gaps (as caused an improper fit mask) over 60% decrease efficiency, implying future mask design take into account issues "fit" leakage, while allowing exhaled air vent efficiently. Overall, we find combinations potentially provide protection against transmission particles.
