Surface Inactivation of Highly Mutated SARS-CoV-2 Variants of Concern: Alpha, Delta, and Omicron
Sign Up to like & getrecommendations! Published in 2022 at "Biomacromolecules"
DOI: 10.1021/acs.biomac.2c00801
Abstract: Continued SARS-CoV-2 transmission among the human population has meant the evolution of the virus to produce variants of increased infectiousness and virulence, coined variants of concern (VOCs). The last wave of pandemic infections was driven… read more here.
