A term used to describe the branch of biology (or is it a branch of physics?) that tries to quantify biological processes and components using rigorous physical methods. Biophysicists work on many different scales. At the tissue level, biophysicists study electrophysiology, the nature of nerve impulses, cardiac rythms, etc. They also study muscle behavior, trying to understand how muscles react to stress and physical conditions. On cellular level, biophysics concerns itself with membrane physics, how do cells move and change shape, and other large scale cellular processes. At the molecular level, biophysicists try to ascertain structures for protein, DNA, RNA and biomolecules. They look at dynamics of molecular interactions and factors contributing to function at the molecular level.
