LATERAL PHASE SEPARATION OF CONFINED MEMBRANES

We consider the membranes interacting via short, intermediate and long stickers. The effects of the intermediate stickers on the lateral phase separation of the membranes are studied via mean-field approximation. The critical potential depth of the stickers increases in the presence of the intermediate sticker. The lateral phase separation of the membrane is thus suppressed by the intermediate stickers. Considering the membranes interacting with short and long stickers, the effect of confinement on the phase behavior of the membranes is also investigated analytically.
