The safe and successful application of nanotechnology in the biological realm remains a challenge due to the inherent multi-scale nature of biology. Engineering nanoBIO devices requires the knowledge of how nanotechnology-based devices interact with biological systems at the protein, cell, tissue, and organ levels. The Engineered nanoBIO node at Indiana University (IU) develops a powerful set of integrated computational nanotechnology products that address this complex, multiscale problem in both education and research and facilitate the discovery of customized, efficient, and safe nanoscale devices for biological applications. These apps, tools, and frameworks span the range from nanoscale particles (nano) to cellular scale structures (micro) to tissue scale morpohologies (macro).

COVID19 tissue simulator

This model simulates replication dynamics of SARS-CoV-2 (coronavirus / COVID19) in a layer of epithelium. It is being rapidly prototyped and refined with community support. 

In this model, SARS-CoV-2 (coronavirus / COVID19) infects a single cell, or a solution of virions is administered to the extracellular space. The virus is uncoated to explose viral RNA, which synthesizes viral proteins that are assembled into a virion. Assembled virions are exported to the environment, where they can diffuse and infect other cells. In the extracellular space, virions adhere to ACE2 receptors and get internalized through endocytosis. Internalized ACE2 receptors release their virus cargo and are recycled back to the surface.

The model includes a basic pharmacodynamic response (to assembled virions) to cause cell apoptosis. Apoptosed cells release some or all of their internal contents, notably including virions.
