Virus like particles (VLPs) are a type of nanoscale particles similar to viruses, with structures similar to real viruses but without viral genes, thus possessing high biological safety. VLPs are particles formed by assembling viral structural proteins, which are similar in size and shape to natural viruses. VLPs have the immunogenicity of natural viruses, but they do not have infectivity or replication ability. By using the VLP technology platform, membrane proteins with natural conformations can be displayed on the surface of these virus like particles. This ability makes their application in immunity and antibody screening valuable.
