Concept explainers

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.

Therefore, dependent on the surface properties, nanomaterials efficiently adsorb biomolecules and form a so-called biomolecular corona. This passive, nontargeted adsorption might be utilized to bind viruses, provided that the selected nanomaterial is relatively biocompatible. Viral surface proteins are often modified by sugar moieties or encompass positively charged amino acid patches that bind to lectins or glycosaminoglycans (GAGs) of heparan sulfate…
