Liquid Crystal Composition and Method of Use

The present invention provides a method, system and composition for controlled compound delivery, the composition comprising a liquid crystal carrier and a compound to be delivered. An external stimulus can be applied to control transition of the liquid crystal from a first phase having a first capacity for retention of the compound to a second phase having a second capacity for retention of the compound. The 'capacity for retention1 is the ability of the liquid crystalline matrix to reduce the apparent diffusion rate of the compound within the matrix to less than that in bulk solvent coexisting with the carrier, such as excess water, bodily fluid or other polar liquid. Thus, the transition from a first phase to a second phase can provide controlled release, on-demand delivery of the compound.
