At the time of writing,the coronavirus disease(COVID-19)has affected 212 countries and territories across the globe.According to the world health organization(WHO),a total number of 4,735,622 confirmed cases,including 316,289 deaths was reported[1].In the fight against COVID-19,nurses,doctors,and other healthcare workers are in the front line of the battle bearing the higher risk of infection[2].The International Council of Nurses(ICN)gathered further information to suggest that more than 90,000 healthcare workers have been infected worldwide[3].Personal protective equipment(PPE)shortage is one of the key factors increasing the infection risk for the medical staffs.Therefore,finding alternative ways to lower the infection risk has become an urgent problem to be solved. 展开更多
