The invention provides a method for lubricating one or more surfaces, comprising applying gel-phase liposomes onto said one or more surfaces, wherein the temperature of said surface(s) at the time of lubrication is below the phase transition temperature Tof said liposomes. The method can be used for lubricating non-biological surfaces, and also for lubricating the surfaces of a biological tissue in a mammalian subject, e.g., for treating joint dysfunction.

Phosphatidylcholine lipid liposomes as boundary lubricants in aqueous media

A method of recovering a petroleum from an underground source thereof comprising injecting into said underground source a petroleum displacement agent comprising a fluid and a modified liposome, said liposome being present in an amount sufficient to lower the interfacial tension between said fluid and said petroleum to below about 10 millidynes and the displacement agent.
