제목 Alginate microspheres incorporating poly(hydroxyethyl acrylate-co-coumaryl acrylate-co-2-ethylhexyl acrylate) : Effect of temperature and UV irradiation on FITC-dextran release
초록 Alginate microspheres incorporating poly(hydroxyethyl acrylate-co-coumaryl acrylate-co-2-ethylhexyl acrylate) (P(HEA-CA-EHA)) were prepared using the water droplets of W/O emulsion as a template. P(HEA-CA-EHA) was prepared by a free radical reaction and the HEA/CA/EHA molar ratio was calculated to be 96.1: 2.0: 1.9 on the 1H NMR spectrum. The copolymer exhibited a lower critical solution temperature around 27 ℃ in distilled water. The CA residues of the copolymer were readily dimerized by UV irradiations in the presence of alginate. The resulting microspheres were subjected to a UV (365 nm) irradiation for the cross-linkage of P(HEA-CA-EHA). The irradiation of UV (254 nm) to the UV(365nm)-treated microsphere promoted the release of FITC-dextran (MW.4,000).
