The rapid spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposed the absence of wide-spectrum antiviral drugs. Owing to this limitation, the worldwide infection rate of SARS-CoV-2 could not be pharmacologically slowed down. The current situation has also exposed the medical vulnerability to viral infections that may lead to another pandemic.
In the past, nanotechnology has offered various direct and indirect solutions to combat viral diseases such as HIV, herpes simplex, respiratory viruses, and human papillomavirus. This article discusses how nanotechnology is being used to combat the current COVID-19 pandemic.
