    • The present invention provides a method of producing a planar lipid bilayer on a solid support. With this method, a solution of lipid vesicles is first deposited on the solid support. Next, the lipid vesicles are destabilized by adding an amphipathic peptide solution to the lipid vesicle solution. This destabilization leads to production of a planar lipid bilayer on the solid support. The present invention also provides a supported planar lipid bilayer, where the planar lipid bilayer is made of naturally occurring lipids and the solid support is made of unmodified gold or titanium oxide. Preferably, the supported planar lipid bilayer is continuous. The planar lipid bilayer may be made of any naturally occurring lipid or mixture of lipids, including, but not limited to phosphatidylcholine, phosphatidylethanolamine, phosphatidylserine, phosphatidylinsitol, cardiolipin, cholesterol, and sphingomyelin.
    • 本发明提供了一种在固体支持物上制备平面脂双层的方法。 使用该方法,首先将脂质囊泡溶液沉积在固体支持物上。 接下来,通过向脂质囊泡溶液中加入两亲肽溶液使脂质囊泡不稳定。 这种不稳定性导致在固体支持物上产生平面脂双层。 本发明还提供了一种支撑的平面脂质双层,其中平面脂质双层由天然存在的脂质制成,并且固体支持物由未改性的金或氧化钛制成。 优选地,支撑的平面脂质双层是连续的。 平面脂质双层可以由任何天然存在的脂质或脂质混合物制成,包括但不限于磷脂酰胆碱,磷脂酰乙醇胺,磷脂酰丝氨酸,磷脂酰胰岛素,心磷脂,胆固醇和鞘磷脂。
