Medical nanotechnology research for COVID-19

26 июня, 2020 - 11:01
The only options to control and deal with the spread of the Severe Acute Respiratory Syndrome Virus 2 (SARS-CoV-2) are fast, cheap, reliable, and portable means of diagnosing COVID-19 infection (the name of disease caused by SARS-CoV-2); therapeutics to treat the infected; and vaccines to rapidly build up immunization of large parts of the global population. The current crisis demands an urgent analysis of all the available nanotechnology tools. While nanomedicine strategies are in use for the design of the vaccine carriers, there are not enough other nanotechnology approaches being explored to tackle the current outbreak.
