Abstract

Det beskrives mikropartikJer med ensformig sfærisk utforming, som utviser en meget smal størrelsesfordeling. De består helt eller delvis av et lineært vannuoppløselig polysakkarid, fortrinnsvis av 1,4-a-D-polyglukan og kan videre spesielt inneholde biologisk nedbrytbare polymerer og/eller virkestoffer. Mikropartiklene er blant annet egnet for den kontrollerte frigivning av virkestoffer. De blir fremstilt gjennom oppløsning av 1,4-a-D-polyglukan eller polysakkaridet i løsemiddel, innføring av oppløsningen i et felningsmiddel, kjøling av blandingen og utskillelse av de dannede partiklene.
