Micropattern formation in supported lipid membranes.
Phospholipid vesicles exhibit a natural tendency to fuse and assemble into a continuous single bilayer membrane on silica and several other substrate materials. The resulting supported membrane maintains many of the physical and biological characteristics of free membranes, including lateral fluidity. Recent advances, building on the supported membrane configuration, have created a wealth of op...
متن کاملCritical point fluctuations in supported lipid membranes.
In this paper, we demonstrate that it is possible to observe many aspects of critical phenomena in supported lipid bilayers using atomic force microscopy (AFM) with the aid of stable and precise temperature control. The regions of criticality were determined by accurately measuring and calculating phase diagrams for the 2 phase L(d)-L(o) region, and tracking how it moves with temperature, then ...
متن کاملLong-Range Interaction Forces between Polymer-Supported Lipid Bilayer Membranes.
Much of the short-range forces and structures of softly supported DMPC bilayers has been described previously. However, one interesting feature of the measured force-distance profile that remained unexplained is the presence of a long-range exponentially decaying repulsive force that is not observed between rigidly supported bilayers on solid mica substrate surfaces. This observation is discuss...
متن کاملTethered and Polymer Supported Bilayer Lipid Membranes: Structure and Function
Solid supported bilayer lipid membranes are model systems to mimic natural cell membranes in order to understand structural and functional properties of such systems. The use of a model system allows for the use of a wide variety of analytical tools including atomic force microscopy, impedance spectroscopy, neutron reflectometry, and surface plasmon resonance spectroscopy. Among the large numbe...
متن کاملMolecular transport and organization in supported lipid membranes.
The mechanism by which vesicles spontaneously form supported lipid bilayer membranes on glass surfaces is becoming better understood and this knowledge is the basis of a technology of patterning membrane arrays and controlling composition. Controlled interactions between supported membranes and cells, particularly from the immune system, provide direct insight into cell-cell surface interactions.
