Research Interests

Multicomponent mixtures of complex molecules have competing interactions of different length scales which can be used to design a large variety of assemblies with important technological and biomedical applications. We analyze co-assemblies of cationic and anionic biological and synthetic molecules and their stability in different ionic media by using a combination of liquid theory and solid state physics techniques. The association of chemically incompatible charged molecules often results in surface charge heterogeneities which lead to hierarchical organizations via charge polarizability. Surface composition heterogeneities are a result of the competition of electrostatic interactions, which favor mixing of opposite charges, and specific interactions and packing constraints which favor segregation of the components.

We analyze the physical properties of mixtures of cationic and anionic amphiphiles co-assembled into lipid membranes, vesicles and cylindrical micelles. We also analyze surface patterns induced by the adsorption or confinement of self-attracting charged biomolecules onto oppositely charged flat and curved surfaces, such as cationic proteins onto actin, and determine the attraction mechanism among surfaces with charge heterogeneities.

We also investigate the thermodynamics, statistics and dynamics of multicomponent complex fluids. In particular, we analyze immiscible molecular fluids including interface adsorption of minority components and phase segregation kinetics. In solutions containing copolymers, for example, the interface adsorption is enhanced and a large variety of structures with unique applications including inverted micelles for drug delivery are obtained.
