“…This indicates that TR-DHPE molecule is likely to accumulate at the spreading edge region. Similar phenomenon has already been found and explained by other group [13]. The self-spreading bilayer on the nano-channel substrate with l = 0.5, 5, 20 µm were shown in Fig.…”

The self-spreading behavior of DMPC bilayer containing TR-DHPE molecule was observed in the presence of channel-type nano-architecture (nano-channel). The concentration of TR-DHPE at the spreading edge region was gradually decreased by passing through the nano-channel. The filtering efficiency was increased by elongating the channel-length, which was explained by considering a formation of a local compressed state of the spreading bilayer in the elongated channel region. In addition to the channel length, the filtering effect was found to be tuned by the channel angle (entrance angle). These two dependencies are important for precise control of filtering efficiency and selectivity.

“…There have been only a few studies of the specific factors that govern bilayer-surface interactions. [9][10][11] More extensive investigations have been performed on the related subjects of supported bilayer-supported bilayer, surfactant-surface, and silica-silica interactions. [12][13][14][15][16] We have found that it is possible to partition fluid-supported membranes into corralled regions that retain their fluidity using simple mechanical scratches.…”

Formation and Spreading of Lipid Bilayers on Planar Glass Supports

The fusion and spreading of phospholipid bilayers on glass surfaces was investigated as a function of pH and ionic strength. Membrane fusion to the support was favorable at high ionic strength and low pH for vesicles containing a net negative charge; however, neutral and positively charged vesicles fused under all conditions attempted. This result suggests that van der Waals and electrostatic interactions govern the fusion process. Membrane spreading over a planar surface was favorable at low pH regardless of the net charge on the bilayer, and the process is driven by van der Waals forces. On the other hand membrane propagation is impeded at high pH or on highly curved surfaces. In this case a combination of hydration and bending interactions is primarily responsible for arresting the spreading process. These results provide a framework for understanding many of the factors that influence the effectiveness of scratches on planar supported bilayers as barriers to lateral diffusion and lead to a simple method to heal these scratches.

“…17 The difference in surface free energy between a bare and lipid bilayer-coated glass surfaces under water is the driving force that drags the bilayer from an area of excess lipid to uncovered areas. 18,19 Other methods to prepare supported membranes include the Langmuir-Blodgett deposition, 15 spin coating, 20 evaporation induced self-assembly, 21 and more recently, dip-pen technology. 8 Each of these methods has inherent advantages with respect to the applications in which they will be used.…”
