A coronavirus virion (particle) is spherical, averaging around 125 nanometers in diameter. Compare that to bacteria’s 1,000-nm size. It’s a grape compared to a grapefruit.

In the current CG model of the SARS-CoV-2 virion, a particle-based phenomenological simulation was used to describe the lipid envelop, and membrane and envelop proteins were modeled as rigid bodies.

Scientists Image A Single HIV Particle Being Born Date: May 26, 2008 Source: Rockefeller University Summary: By using a specialized microscope that only illuminates the cell's surface, scientists ...

(F) Virion particle counts for three early clade variants (A.2.2, Beta and Delta) and three Omicron sub-lineages (G) Schematic showing the effect of TMPRSS2 inhibitor Nafamostat on virus entry at ...

Their computer simulation begins by rendering the virus as a relatively large, 73-nanometer ball of loosely packed lipids. This ball then relaxes down into a smaller, 59-nanometer virion within ...

6 facts about coronavirus, from a biomedical researcher. Viruses are the most common biological entities on Earth. Experts estimate there are around ...

A new technique to examine how proteins interact with each other at the level of a single HIV viral particle has been developed by an interdisciplinary team of scientists. The technique allows ...

The HIV virion is the virus particle that spreads the deadly AIDS infection from cell to cell. “On the molecular scale it’s a huge object that probably involves a billion total atoms. You would never ...

By zeroing in at the cell’s surface, the team became the first to document the time it takes for each HIV particle, or virion, to assemble: five to six minutes. “At first, ...
