SARS-CoV-2 viral infection at atomic resolution. Counting eight viruses, each of which has spikes (big protrusions) and E membrane proteins (small protrusions) rainbow colored and a core in sienna color, this picture shows how the viruses approach the cell membrane (green). The ACE2 receptors are colored magenta. The field of view is 1 micrometer.
