Development and application of coarse-graining force field in self-assembled systems


Molecular modeling is an important tool for analysis of mechanism at nanoscopic level, contributing to the understanding of the phenomena and interpretation of experimental data. On the one hand, the set of computational techniques has been unceasingly developed, pursing better force fields that could reproduce the experimental data with precision. By other hand, another class of models (coarse-grained) has been worked and also developed. Coarse-grained models have less interactions sites or described by effective potentials, allowing to probe large spatial and temporal scales. The goal of this project is the development of a coarse-grained force Field (ELBA) for self-assembled systems (e.g., biomembranes, peptides, copolymers, surfactants) that reproduce in a consistent way the electrostatic and Van der Waals interactions. The coarse-grained force field will help in the interpretation of experiments results. (AU)
