“…The SL-chitosan binds to hemagglutinin protein on the surface of an influenza particle, which is responsible for viral attachment to the host cell surface via binding with surface glycoligands such as SL. Guo et al 137 reported on antiviral mechanism of a combined biological agent consisting of chitosan oligosaccharide and cytosinpeptidemycin (CytPM-COS). CytPM-COS effectively inhibited tobacco mosaic virus (TMV), suppressed viral RNA and capsid protein accumulation and triggered production of ROS and induced upregulation of various defence responsive genes in the tobacco plants.…”

Viral infections are a serious health challenge, and the COVID-19 pandemic has increased the demand for antiviral measures and treatments for clean surfaces, especially in public places. Here, we review a range of natural and synthetic surface materials and coatings with antiviral properties, including metals, polymers and biopolymers, graphene and antimicrobial peptides, and their underpinning antiviral mechanisms. We also discuss the physico-chemical properties of surfaces which influence virus attachment and persistence on surfaces. Finally, an overview is given of the current practices and applications of antiviral and virucidal materials and coatings in consumer products, personal protective equipment, healthcare and public settings.

With the industrial developments in recent times, the textile industry also needs sustainable and environmental-friendly resources. Today’s world has been overburdened with the use of synthetic or hazardous materials in day-to-day life. Chitosan polymer obtained from chitin deacetylation, having a lot of properties beneficial to mankind without being hazardous to environment and humans is currently gaining popularity for research and development all over the globe. Antimicrobial and antiviral textile finishing with the help of chitosan is a new trend in the textile field. Also, chitosan having good adsorption properties finds its application in textile effluent treatments. This review reports and discusses multifunctional finishing and dyeing of textiles with chitosan and highlights its application for textile wastewater treatment.

“…Lei et al also studied the antiviral effects of chitosan and found that chitosan obtained from Musca domestica L housefl's larvas has an antiviral effect, based on tests conducted on Autographa californica Multicapsid Nucleopolyhedrovirus (AcMNPV) and Bombyx mori nuclear polyhydrosis virus (BmNPV) [102]. Wu et al studied a combination of cytosinpeptidemycin and chitosan oligo-saccharide, found it has an antiviral effect on TMS, most likely due to several mechanisms, such as a suppression effect of the viral RNA, an effect on the virus's subcellular localization as well as punctate formation of TMV MP in some plants leaves [103]. As opposed to the above, Ishihara found chitosan to be ineffective against the Influenza A virus [83].…”

Antiviral polymers are part of a major campaign led by the scientific community in recent years. Facing this most demanding of campaigns, two main approaches have been undertaken by scientists. First, the classic approach involves the development of relatively small molecules having antiviral properties to serve as drugs. The other approach involves searching for polymers with antiviral properties to be used as prescription medications or viral spread prevention measures. This second approach took two distinct directions. The first, using polymers as antiviral drug-delivery systems, taking advantage of their biodegradable properties. The second, using polymers with antiviral properties for on-contact virus elimination, which will be the focus of this review. Anti-viral polymers are obtained by either the addition of small antiviral molecules (such as metal ions) to obtain ion-containing polymers with antiviral properties or the use of polymers composed of an organic backbone and electrically charged moieties like polyanions, such as carboxylate containing polymers, or polycations such as quaternary ammonium containing polymers. Other approaches include moieties hybridized by sulphates, carboxylic acids, or amines and/or combining repeating units with a similar chemical structure to common antiviral drugs. Furthermore, elevated temperatures appear to increase the anti-viral effect of ions and other functional moieties.
