Molecular Landscapes by David S. Goodsell

Respiratory Droplet, 2020

This painting shows a cross section through a small respiratory droplet, like the ones that are thought to transmit SARS-CoV-2. The virus is shown in magenta, and the droplet is also filled with molecules that are present in the respiratory tract, including mucins (green), pulmonary surfactant proteins and lipids (blue), and antibodies (tan).

The painting was created as part of the show "New Ways of Living" with SciCommMake.

The image also appears on the cover of the March-April 2021 issue of American Scientist.
