Disclosed herein are glycosylated amphiphilic molecules composed of hydrophobic "tails" and hydrophilic "heads" that self align to form a membrane at the interface of a polar solvent and a non-polar liquid or a solid. The present invention is directed to a solid state membrane, typically a thin film, composed of a non-polar solid material having the hydrophobic "tail" of a glycosylated amphiphilic molecule embedded in or linked to its surface such that the hydrophilic "head" protrudes from the solid surface and presents useful properties to the surrounding environment. A membrane or film in accordance with the present invention is produced when a non-polar liquid, in the presence of a polar solvent and an amphiphilic biological compound, undergoes a transformation from liquid to solid, through thermal, chemical or radiative means, with the resultant effect that the amphiphilic molecule is affixed or "locked" to the surface, more particularly the hydrophobic ends of the amphiphilic compounds are mechanically or chemically linked to or embedded in the non-polar solid. The membrane and micelles produced therefrom remain stable even in the absence of the polar solvent, thereby allowing the hydrophilic components of the amphiphilic compounds to present useful properties at the surface thereof. |
