“…150 It has also been found to be an effective antiviral agent in the packaging of materials. 154 Kumar et al 155 developed nanostructured ZnO coated antiviral silk fabric using electrospinning followed by the atomic layer deposition (ALD) technique for personal protective equipment (PPE) applications. The developed ZnO based nanocomposite fabric exhibited 85% better antibacterial activity as compared to the control silk fabric and also showed substantial superoxide dismutase-mimetic activity.…”

“…The former exerts roles via the interaction manners between the metal-based material and virus proteins, including attraction, denaturation, or destruction effects with the virus. The latter relies on an external stimulus like light irradiation, which induces the fiber coating to generate ROS or heat to damage virus proteins . Notably, the particle size of the photocatalysts is required to be nanoscale due to their limited response spectral range, which unavoidably increases difficulties to embed them into fiber surfaces.…”

The outbreak of COVID-19 provided a warning sign for society worldwide: that is, we urgently need to explore effective strategies for combating unpredictable viral pandemics. Protective textiles such as surgery masks have played an important role in the mitigation of the COVID-19 pandemic, while revealing serious challenges in terms of supply, cross-infection risk, and environmental pollution. In this context, textiles with an antivirus functionality have attracted increasing attention, and many innovative proposals with exciting commercial possibilities have been reported over the past three years. In this review, we illustrate the progress of textile filtration for pandemics and summarize the recent development of antiviral textiles for personal protective purposes by cataloging them into three classes: metal-based, carbon-based, and polymer-based materials. We focused on the preparation routes of emerging antiviral textiles, providing a forward-looking perspective on their opportunities and challenges, to evaluate their efficacy, scale up their manufacturing processes, and expand their high-volume applications. Based on this review, we conclude that ideal antiviral textiles are characterized by a high filtration efficiency, reliable antiviral effect, long storage life, and recyclability. The expected manufacturing processes should be economically feasible, scalable, and quickly responsive.

“…Further, it also showed an 85% improvement in antibacterial activity. The effectiveness of the fabric was tested using coronavirus and rhinovirus [ 103 ] and the results demonstrated an ≈95% reduction in both viruses and following 1 h of exposure. After 2 h, an ≈99% reduction was reported.…”

Reducible metal oxide nanozymes (rNZs) have been a subject of intense recent interest due to their catalytic nature, ease of synthesis, and complex surface character. Such materials contain surface sites which facilitate enzyme‐mimetic reactions via substrate coordination and redox cycling. Further, these surface reactive sites have been shown to be highly sensitive to stresses within the nanomaterial lattice, the physicochemical environment, and to processing conditions occurring as part of their syntheses. When administered in vivo, a complex protein corona binds to the surface, redefining its biological identity and subsequent interactions within the biological system. Catalytic activities of rNZs each deliver a differing impact on protein corona formation, its composition, and in turn, their recognition, and internalization by host cells. Improving our understanding of the precise principles that dominate rNZ surface‐biomolecule adsorption raises the question of whether designer rNZs can be engineered to prevent corona formation, or indeed to produce “custom” protein coronas applied either in vitro, and pre‐administration, or formed immediately upon their exposure to body fluids. Here, we consider fundamental surface chemistry processes and their implications in rNZ material performance. In particular, we discuss material structures which inform component adsorption from the application environment, including substrates for enzyme‐mimetic reactions.This article is protected by copyright.
