Capsids

A capsid is the protein shell that encloses the genetic material of a virus, forming the virus particle. Capsids are composed of identifying proteins and other molecules that allow viruses to bind to cells, penetrate them, and inject their genetic material. Understanding capsids and the molecules they contain is important to the development of antiviral treatments, as targeting capsids can be an effective means of preventing infection. In addition, capsids are increasingly being studied for their potential uses in biotechnology and nanotechnology. In nanotechnology, capsids can be used as nanocontainers for drug delivery and as templates for creating new nanomaterials.
