In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers.

Nanoparticle vaccine could protect against animal viruses including future SARS-CoV-2 variants

A recent study published in the Science journal depicted that mosaic receptor-binding domain (RBD) nanoparticles immunize from diverse sarbecovirus challenges, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), among animal models.
