Abstract

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 Tm of 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.
