Developments of models for biomolecules-inorganic surfaces and nanostructures interactions

The research line was started more than a decade ago and it continuously develop Force Field parameters to simulate protein-surface and protein-NP interfaces. The originally in house developed GolP force field with explicit protein-Au(111) interaction parameters is freely downloadable (http://web.fisica.unimo.it/prosurf/toolbox.html) together with more recent force field parameters for various Au nanoclusters. The parameters allow to access various levels of computational description of protein-surface interactions, from classical MD to Brownian Dynamics to Coarse Grained.

In addition to protein and peptides also classical force fields for DNA on Au(111) surfaces and Au nanoparticles are costantly developed by means of first-principles electronic structure calculations.
