With over 200 COVID-19 vaccine trials currently underway globally, nanotechnology is being pivoted for COVID-19 applications. Nanoparticles and viruses operate on the same scale, and thus there are various nanotechnological aides which are being used in the development of potential vaccines. Nanoparticles are capable of entering the cell through biological channels, and can deliver antigens there. Besides delivering antigens themselves, nanoparticles can also be enlisted to provide adjuvants to cells.
