Surface Alterations to Impart Antiviral Properties to Combat COVID-19 Transmission

Siddiquie, Reshma Y.; Agrawal, Amit; Joshi, Suhas S.

A global epidemic caused by highly transmittable COVID-19 is causing severe loss of human life. In this study, two aspects of reducing transmission of COVID-19 virus, due to surface contact, are discussed: first refers to the effect of nanocarbon fullerene C(60) coating on surface, that causes lipid peroxidation on the phospholipid layer present in the outer envelope of COVID-19; the second aspect refers to creating hydrophobic surfaces by texturing them, so that the contact area between virus and surface is minimized due to the presence of entrapped air between the topographies. These can be similar to micro-/nano-multiscale textured surfaces that have anti-biofouling properties. Fullerene-coated surfaces can be seen as a possible solution to decrease the adhesion of virus on the surface, as they will be hydrophobic as well as toxic to the envelope.
