Polymeric drug-loaded microparticles

Both W/O/W and O/W/O emulsions have attracted considerable attention because of their potential applications in food science [4-7], cosmetics [8-10] and pharmaceutics [11]. In particular, there have been many studies on the pharmaceutical applications of W/O/W emulsions because the internal aqueous droplets can contain water-soluble drugs for controlled release or targetable delivery [12-14]. Solid microcapsules loaded vhth bioactive polymers are also prepared from W/O/W droplets by the solvent evaporation method [15-18]. Other applications studied thus far include the synthesis of shaped polymeric microparticles [19] and the use of the intermediating phase as the permeation membrane in separation technology [20-25].
