摘要

Understanding transport properties of solvent such as diffusion and viscosity at interfaces withbiomacromolecules and hard materials is of fundamental importance to both biology andbiotechnology. Our study utilizes equilibrium molecular dynamics simulations to calculate solventtransport properties at a model peptide and microarray surface. Both diffusion and selectedcomponents of viscosity are considered. Solvent diffusion is found to be affected near the peptideand surface. The stress-stress correlation function of solvent near the hard surface exhibits long timememory. Both diffusion and viscosity are shown to be closely correlated with the densitydistribution function of water along the microarray surface.
