Coating for capturing and killing viruses on surfaces

Disclosed herein is a nano-coating platform that is designed to ‘capture’ and ‘kill’ (i.e. inactivate) virus species to prevent surface to surface contamination/transmission and thereby the spread of novel viruses. The platform is comprised of alternating layers of charged polymers (producing a multi-layer coating). The cationic layer may be grafted with oligomeric species, chosen to bind strongly to unique/specific virus surface features, thereby mediating capture of the virus (with the choice of oligomeric species allowing generalization to a given virus). Natural light (excitation) to UV (local emission) up-converting nanoparticles are seeded into the anionic layer and mediate the inactivation (‘killing’) of the bound virus species.

Antimicrobial guanidinium and thiouronium functionalized polymers

Antimicrobial cationic polycarbonates and polyurethanes have been prepared comprising one or more pendent guanidinium and/or isothiouronium groups. Additionally, antimicrobial particles were prepared having a silica core linked to surface groups comprising a guanidinium and/or isothiouronium group. The cationic polymers and cationic particles can be potent antimicrobial agents against Gram-negative microbes, Gram-positive microbes, and/or fungi.
