POLYELECTROLYTES AND CHARGED COLLOIDS

We are interested in the electrostatic properties of DNA, nucleosomes and chromatin. We use reconstituted in vitro model systems to understand the conformation and interactions of these objects according to their physico-chemical environment (osmotic pressure, ionic strength, presence of polycations and basic proteins, ...).
We also pay attention to their organisation and structural properties when they form dense phases, with a special interest to the geometry and defects of these systems.
