摘      要：The ongoing coronavirus disease 2019(COVID-19)pandemic is a serious challenge faced by the global *** scientists can help medical workers and biomedical scientists,engineers,and practitioners,who are working on the front line,to slow down and eventually contain the spread of the COVID-19 *** review is focused on the physicochemical characteristics,including composition,aerodynamics,and drying behavior of respiratory droplets as a complex and multicomponent soft matter system,which are the main carrier of the virus for interpersonal *** distribution and dynamics of virus particles within a droplet are also *** the characteristics of virus-laden respiratory droplets can lead to better design of personal protective equipment,frequently touched surfaces such as door knobs and touchscreens,and filtering equipment for indoor air *** an understanding also provides the scientific basis of public policy,including social distancing rules and public hygiene guidelines,implemented by governments around the world.
