چکیده
General expressions of self-energy and corresponding virial terms for electrostatic interactions in dissipative particle dynamics simulations are derived in this article. In the lattice-sum electrostatics, we found the essential process is to solve the electric field equation of each individual point charge. Strong inward pressure caused by the self-energy is eliminated by subtracting the corresponding virial from the total virial. The resulting method is tested by simulating cationic lipid bilayers in constant pressure ensemble.

Appearing as a computational microscope, MD simulation can ‘zoom in’ to atomic resolution to assess detailed interactions of a membrane protein with its surrounding lipids, which play important roles in the stability and function of such proteins. This study has employed the molecular dynamics (MD) simulations, to determine the effect of added DMPC or DMTAP molecules on the structure of D...

The fusion of lipid bilayers is studied with dissipative particle dynamics simulations. First, to achieve control over membrane properties, the effects of individual simulation parameters are studied and optimized. Then, a large number of fusion events for a vesicle and a planar bilayer are simulated using the optimized parameter set. In the observed fusion pathway, configurations of individual...

متن کاملImproved dissipative particle dynamics simulations of lipid bilayers.
The authors introduce a new parameterization for the dissipative particle dynamics simulations of lipid bilayers. In this parameterization, the conservative pairwise forces between beads of the same type in two different hydrophobic chains are chosen to be less repulsive than the water-water interaction, but the intrachain bead interactions are the same as the water-water interaction. For a cer...
