Soft matter, biophysics

The states of aggregation in condensed matter may be simple, as in a gas or in a crystalline solid, but may become very complex in biological systems. Atoms and molecules combine themselves to form macromolecules, such as proteins, which get together to create rich structures, such as micelles and vesicles, which in turn become the building blocks of complex states of aggregation, such as those found in lyotropic liquid crystals, polymeric gels, surfactants, and other biological systems. The physical-chemical properties of these systems, especially those that may be useful in medical biology, are investigated by the Group of Complex Fluids. The same concern drives the investigation carried out by the Group of Biophysics. The main topic of study by this group is molecular biophysics, analyzed by various experimental techniques including electronic paramagnetic resonance. Biological imaging by nuclear magnetic resonance is the object of study at the Magnetic Resonance Laboratory. Mechanical measurements in living cells and complex fluids such as polymeric gels and surfactants are performed in the Celular Rheology Laboratory. Theoretical approaches in complex fluids and molecular biophysics as well as in rheology include the use of models within the framework of statistical mechanics and molecular quantum mechanics.
