    The aim of this project is to include electrostatics into the mean field models of interactions of lipid membranes with self-assembled nano-objects including functional biomimetic polymers, peptides, polymeric micelles and polymer therapeutic complexes/conjugates in order to enable the intelligent design of new materials with improved bilayer modifying properties. (see IPEC Solver)

    This study may provide the molecular basis for the cytotoxicity of nano-objects and indicate the ways to reduce it. Combination of the Poisson-Boltzmann theory with the Single Chain Mean Field theory can test the inferred mechanisms for the interaction of charged nano-objects with phospholipid bilayers allowing to get insight into membrane association mechanisms.

This is particularly the case for relatively large boundary conditions leading to rapid changes of ...
