Research Interest: Complex Fluids
The interest of our group is to study the
behavior of chemical and biological systems where complex molecules are present.
We particularly seek simple models that are able to explain the properties of
these systems.
- Why does DNA form compact structures? We develop a theory
for polyelectrolyte solutions that might lead to a better understanding of the
DNA in the presence of salt or organic solvents. We also propose a complex
made of one charged polyelectrolyte and amphiphilic molecules. This system has
applications for drug deliver mechanism.
- When does negative macroions move toward an electric
field? We study the charge reversal of charged colloid suspensions.
- How does an ion enter in an ionic channel? We explore the
behavior of ionic channels. .
- Why does water have themodynamic and dynamic anomalies?
We look for the simple mechanism that explain the presence of such
anomalies.
