Abstract

A találmány olyan mikrorészecskékkel foglalkozik,amelyeknek egységes, gömbszerű alakjuk van és nagyon szűkméreteloszlást mutatnak. Ezek a mikrorészecskék egészben vagy részbenvalamely lineáris, vízben oldhatatlan poliszacharidból, előnyösen 1,4-a-D-glukánból állnak, de ezek tartalmazhatnak más, biológiailaglebontható polimereket és/vagy aktív alkotórészeket is. Ezeket többekközött alkalmazni lehet aktív alkotórészek szabályozottkibocsátásához. Ezek előállítása úgy megy végbe, hogy az 1,4-a-D-poliglukánt vagy valamely egyéb poliszacharidot oldószerbenfeloldanak, az oldatot valamely kicsapószerrel összekeverik, akeveréket lehűtik és a keletkezett részecskéket elkülönítik.
