Biological Physics

Biological physicists use principles of physics to understand biological processes. The spatial scale of these processes spans the single molecule to the biological network. On the single molecule level, physicists make significant contributions in the development of experimental methods that illuminate molecular conformations, measure interactions with other molecules and monitor the formation of scaffolding that forms the cellular supporting environment. On the network level, collective behaviors and systems far from equilibrium prevail, requiring tools from non-linear dynamics and statistical mechanics to quantify these interactions. Fabrication of integrated micro-devices applied to human health also falls under the purview of the biological physicist. These sophisticated tools utilizing state-of-the art technologies improve quality of life and health care as they speed drug delivery and facilitate the diagnosis of disease.

At Georgetown, biological physicists use advanced optical imaging techniques such as high-speed confocal microscopy and optical tweezers to study a variety of systems including properties of cell motility, neurite migration in 3D bio-matrices and biopolymer rheology. Arrays of extracellular microelectrodes are used to study pattern formation in in vitro neural networks. The Georgetown Nanoscience and Microtechnology Lab (GNuLab) is home to a wide range of state-of-the-art fabrication and characterization instruments to develop bio-technologies for the healthcare industry.
