Cellular biophysics is a branch of biophysics that focuses on the physical principles of cell function. It performs a bridging function from the atomic or molecular understanding of proteins, membranes and polynucleotides to the highly complex and highly integrated systems of organelles and whole cells. Finally, the investigation of tissues and organs ties in with medical biophysics.

Current areas of cellular biophysics are intracellular signal dynamics and transport, cell mechanics, molecular motors and electrophysiology. The field has benefited greatly from recent advances in the imaging of living cells that allow spatial and temporal measurement of macromolecules and their function. The control of cellular processes by light (optogenetics) also provides unique possibilities for the investigation of physiological processes. The combination of novel experimental tools with mathematical models is a particular strength of this area.

Section III of the DGfB provides a platform for discussion and collaboration in the field of cellular biophysics. The biennial section conference, which attracts international biophysicists and researchers from related disciplines, is particularly suitable for this purpose. The next section workshop entitled "The workings of ion transporters and channels" will take place from August 9-11, 2019 in Berlin-Wannsee.
