| Outline of Final Research Achievements |
In this study, we investigated environment-friendly synthetic methods for the encapsulation of water-soluble substances in biodegradable poly lactic-co-glycolic acid (PLGA) polymer particles. As a result, PLGA nanoparticles generated using vegetable oil as a continuous phase self-assembled on water droplets to stabilize W/O (Water in Oil) emulsion and then the polymer particles were fused by heating, leading that PLGA microcapsules capable of encapsulating water soluble polysaccharides, proteins and microorganisms have been successfully synthesized.

| Academic Significance and Societal Importance of the Research Achievements |
PLGAは、生体適合性、生分解性、薬物徐放性に優れたポリマー基材であるが、疎水性のため、親水性物質の封入には適していない。また、PLGA粒子の合成には、生体に有害な化学物質が使用される。本研究で合成したPLGAマイクロカプセルは、内相が水であるため、親水性物質の封入が可能であるたけでなく、その合成プロセスにおいて有害な化学物質をまったく使用していないため、環境調和型の薬物送達システムを可能とする。
