Mesoscopic Modeling of Protein-Surface Interactions

Project goals

The project aims to contribute to fundamental understanding of protein adsorption on homogeneous and heterogeneous surfaces. Mesoscopic modeling using dissipative particle dynamics will be employed to systematically study the effect of shape, size and hydrophobicity/hydrophilicity of proteins on their adsorption kinetics. Mesoscale models of proteins and surfaces will be obtained from atomistic simulations of individual proteins in water and individual proteins close to walls using mapping from the atomistic to mesoscopic level. The mesoscopic modeling will be complemented by macroscopic modeling based on kinetic models of adsorption processes and the mesoscopic simulation results will be compared with experiments.

    Mesoskopické modelování interakce proteinů s povrchy

  • Annotation in Czech

    Cílem projektu je přispět k základnímu pochopení mechanismu adsorpce/desorpce proteinů na homogenních a heterogenních površích. Pomocí mesoskopických simulací založených na disipativní částicové dynamice bude systematicky studován efekt tvaru, velikostia hydrofobicity/hydrofilicity proteinů na jejich adsorpční kinetiku. Mesoskopické modely proteinů a povrchů budou navrženy na základě molekulárních simulací jednotlivých proteinů ve vodě a v blízkosti stěn pomocí mapování z atomární na mesoskopickou úroveň. Mesoskopické modelování bude doplněno makroskopickým modelováním založeným na kinetických modelech adsorpčních procesů a výsledky mesoskopických simulací budou přímo srovnány s experimentálními daty.
