Chem: Understanding the surface chemistry of SARS-coV-2 contributes to vaccine development.

August 14, 2020 /--- Based on a recent study, we need to better understand the surface chemical characteristics of the SARS-CoV-2 virus to reduce transmission and accelerate vaccine design.
by researchers at Michigan Tech University, the Uk's National Engineering Laboratory and the University of Edinburgh, said: "The surface chemical characteristics of SARS-CoV-2 are a key factor in their ability to spread under a variety of environmental conditions.
stressed the need to understand how different environmental conditions affect the surface chemistry of SARS-CoV-2.
we generally believe that washing your hands with soap for more than 20 seconds can effectively kill the virus.
is that soap interacts with the virus's surface chemicals, especially with the surrounding lipid or fat shell, causing the virus to rupture.

we can further stop the spread of the virus if we can better reduce the time it lasts on the surface or in the air.
have a unique way of interacting with the surface of an object," said Caryn Heldt, author of the paper.
chemical properties of the virus will change the way the virus interacts with water.
if breathing and water commonly found in the air, such as moisture, involve the virus and the surface of an object, it can really change the way the virus interacts with that surface.
we need to understand how viruses interact with the surface when there is water and no water, but our traditional methods of studying surface chemistry do not detect these low-level viruses.
" Heldt says their article provides a broad overview of the different ways in which researchers can learn more about these surface interactions at the chemical level.
Unlike the virus that causes influenza, SARS-CoV-2 is mainly transmitted by aerosols, or by particles suspended in the air when people speak, sing, cough, or sneeze.
, a postdoctoral research assistant at the University of Edinburgh, said: "For the first time, we have highlighted the potential for the stability of the new SARS-CoV-2 surface under a variety of environmental conditions, including temperature and relative humidity.
" virus is usually more stable in the cold, which may explain why the flu season tends to occur in winter.
the virus that causes COVID-19 does not seem to be so.
, however, the researchers deduced from the effects of heat on molecules that increased heat caused virus particles to move faster and the vibrations of viral molecules to increase, causing them to rupture and cease to be contagious.
further study of the effects of humidity, temperature and other environmental conditions, it is also necessary to explore the effects of pH balance and protein shell on viruses.
better understanding of the surface chemistry of SARS-CoV-2 will help scientists better design vaccines.
