Viruses like COVID-19 are very small. They are nanometer in diameter. To detect and prevent them, nanotechnology is a crucial tool. This review paper reviews the recent progress of nanomedicine in fighting COVID-19. At the beginning, how nanoparticle works in our body is described here. Recent observations of these medicines’ performance are illustrated with some practical case studies. Different types of vaccines based on nanoparticles and their potentiality of fighting COVID-19 are also described. What can be the potential challenges for this technology along with prospects are also discussed. At the end, some nanomedicines have been suggested that can be effective to fight the virus. This paper can be used as a state-of-the-art at this critical moment to the globe for promising nanotechnology-based therapy related to the survival of people from coronavirus.
