Morphology and swelling property of chitosan microapsules and microbeads prepared by W/O emulsion
W/O 에멀젼에 의한 chitosan microcapsule 및 microbead의 morphology와 팽윤성
Abstract
Chitosan microcapsules and microbeads were prepared by W/O emulsion method, and their morphologies were observed through SEM. The microcapsules have skin layer of 8 Um and 250 Um of mean diameter, The swelling test showed higher s welling ability in protic solvents than in aphotic solvents. After containing moth-yl violet in the microcapsules, the release patterns were investigated. The results sho wed that the addition of Iysozyme in pH 5.1 acetate buffer accelerated the re-lease rate. In case of the microbeads, the mean diameter was about 70 Um. The surface of the microbeads showed porous structures. The swelling ability of the beads revealed two times higher than the one of the microcapsules.
