We describe computer simulations of pore formation and membrane rupture of phospholipid bilayers under mechanical and electrical stress. On the nanosecond simulation time scale, pores are induced by a lateral pressure exceeding -200 bar or by an applied electric field of 0.5 V/nm.
Lipid adhesion forces can be measured using several experimental techniques, but none of these techniques provide insight on the atomic level. Therefore, we performed extensive nonequilibrium molecular dynamics simulations of a phospholipid membrane in the liquid-crystalline phase out of which individual lipid molecules were pulled. In our method, as an(More)
