Query: Dissipative particle dynamics simulation of critical pore size in a
  lipid bilayer membrane   We investigate with computer simulations the critical radius of pores in a
lipid bilayer membrane. Ilton et al. (2016) recently showed that nucleated
pores in a homopolymer film can increase or decrease in size, depending on
whether they are larger or smaller than a critical size which scales linearly
with film thickness. Using dissipative particle dynamics, a particle-based
simulation method, we investigate the same scenario for a lipid bilayer
membrane whose structure is determined by lipid-water interactions. We simulate
a perforated membrane in which holes larger than a critical radius grow, while
holes smaller than the critical radius close, as in the experiment of Ilton et
al. (2016). By altering system parameters such as the number of particles per
lipid and the periodicity, we also describe scenarios in which pores of any
initial size can seal or even remain stable, showing a fundamental difference
in the behavior of lipid membranes from polymer films.
