Molecular Dynamics Simulations as a Tool for Accurate Determination of Surfactant Micelle Properties.

Molecular dynamics (MD) simulations were used to characterize the equilibrium size, shape, hydration, and self-assembly of dodecylphosphocholine (DPC) and dodecyl-β-D-maltoside (DDM) micelles. We show that DPC molecules self-assemble to form micelles with sizes within the range reported in the experimental literature. The equilibrium shape of DPC and DDM micelles as well as associated micellar radii are in agreement with small-angle X-ray scattering (SAXS) experiments and theoretical packing parameters.
