Porous substances have received increasing attention in recent years as an alternative for the planar substrates supporting the lipid bilayers in order to surmount the basic problems such as difficulties in protein insertion. In this study, phase separated lipid bilayers containing 1,2-Distearoyl-Glycero-3-Phosphocholine (DSPC) and 1,2-Dioleoyl-Glycero-3-Phosphocholine (DOPC) with a mole ratio of 1:2 were successfully formed on xerogel surfaces. The topology of both the xerogel surfaces and the supported lipid bilayers were investigated with Atomic Force Microscopy (AFM) whereas the domain size calculations and lipid mobility were studied by using epifluorescence microscopy with the inclusion of fluorescent probes at a low concentration. The fluid phase as well as the gel phase was found to be following the xerogel surfaces closely under contact mode imaging conditions. The average domain size of the lipid bilayers on xerogel surfaces cooled with a controlled cooling rate was found to be statistically larger than the size of the similarly prepared domains on mica surfaces that are known to be atomically smooth. The lateral lipid mobility which is a crucial feature for a functional lipid bilayer was confirmed with Fluorescence Recovery After Photobleaching (FRAP) approach. Future work will include the effect of xerogel processing condition changes resulting in different porosities and bead sizes on the lipid bilayer formation and phase separation properties.
