2D surface maps. These maps depict leaflets taken from a variety of lipid bilayer simulations. Red hexagonally packed dots represents gel clusters and black areas indicate the presence of a pore or hole in the leaflet. (a) and (b) depict POPE/POPG (3:1) bilayers at two temperatures, where (a) is near the transition temperature and contains 53% gel, and (b) is in the fluid phase and contains 14% gel. (c) and (d) depict POPC and DPPC bilayers at 297 K, containing 16% and 85% gel respectively. These percentages correspond with the correct phase of each bilayer as 297 K is above the transition temperature for POPC and below that of DPPC. The DPPC map also reveals a smudged appearance to the gel clusters which is indicative of lipids in the tilted \(L_{\beta ^{\prime }}\) phase. (e) depicts an inserted MinD-MTS peptide in a POPE/POPG (3:1) bilayer at 300 K. (f) depicts a leaflet containing a transient water pore established through electroporation in a POPE/POPG (3:1) bilayer at 297 K.
