In addition to mechanistic information, researchers have also evaluated the size and content characteristics of the SARS-CoV-2 particles. Upon analysis of negative-stained SARS-CoV-2 articles by electron microscopy, researchers have determined the diameter of this virus to range between 60 nanometers (nm) to a maximum diameter of 140 nanometers (nm).
In addition to measuring the spherical size of the virus particle, it has also been confirmed that the length of the size tumors that surround the outermost surface of SARS-CoV-2 can vary in length from 9 to 12 nm.
