The present disclosure relates to functional composite particles produced by filling water-soluble or lipid-soluble polymers into changeable liposomes and a method of producing the same. The present disclosure also relates to an evaluation of specialized biochemical characteristics of composites after the composites are produced using the water-soluble or lipid-soluble polymers by selection from groups capable of combining with lipid layers. A protocol according to an embodiment of the present disclosure overcomes the limitations of a conventional water/oil-based single emulsion protocol to prepare single polymer particles or single lipid layered particles and combine liposomes with a variety of polymer groups.
