"Soft matter", within condensed matter physics, includes not only "ordinary" liquids, but also more complex fluids. These complex fluids generally behave as liquids at a molecular scale, and simultaneously show some organization at a supramolecular scale (sometimes there are several different kinds of organization depending on the length scale). The field of application is huge, indeed soft matter is everywhere in our everyday life: cosmetics (creams, shampoos...), food (yoghurts, jellies..), mud, sand, liquid crystals (watches, computer screens), biological objects (cells) among others. The word "soft" refers to the fact that all these objects can be easily deformed, being very sensitive to external parameters (temperature, electric field...), in other words they are fragile.
The research topic named "soft matter and physics-biology interface" of our laboratory gathers very diverse physical systems, from biological materials to industrial plastic materials. Experimental studies concern organization and dynamics of soft matter systems on a wide range of length scale (from the molecular to the macroscopic scale) ; the techniques used are extremely diverse and most of them are available inside the laboratory. They are completed by theoretical studies, modelizations and numerical simulations.
