摘要：

A method for preparing a controlled-release composition for biologically active materials, the composition consisting of amphiphilic substances capable of forming liquid crystalline phases, especially cubic phases, in aqueous medium. The bioactive material is either dissolved or dispersed in the liquid crystalline phase, or alternatively, coated by the liquid crystalline phase. The invention is advantageous from thermodynamical and mechanical points of view, and a rich variety of applications exists.
