Abstract: 본 발명은 소수화된 폴리이소프로필아크릴아미드(Poly(
N -isopropylacrylamide); PNIPAM)가 큐빅상 내부의 수상채널에 고정화되어 제조된 모노올레인 큐빅상(monoolein cubic phase)에 관한 것으로, 폴리이소프로필아크릴아미드의 상전이 온도 이하에서는 포집 성분을 비교적 적게 방출하고, 상전이 온도 이상에서는 포집 성분을 비교적 많이 방출할 수 있는바, 목적 물질을 필요에 따라 조건의 조절을 통해, 포집 상태를 유지할 수도, 방출할 수도 있는 특징이 있다.

Abstract: A poly(N-isopropylacrylamide)-immobilized monoolein cubic phase is provided to release the relatively small amount of the target ingredient at less than phase transition temperature of poly(N-isopropylacrylamide), and release the relatively large amount of the target ingredient at more than phase transition temperature of poly(N-isopropylacrylamide). The poly(N-isopropylacrylamide)-immobilized monoolein cubic phase is manufactured by mixing polyisopropylamide combined with immobilizing material to be immobilized to the aqueous channel within the cubic phase with the target material to be encapsulated into the aqueous channel to prepare the mixed solution; and adding the mixed solution into the monoolein-dissolved solution to form the transparent gel.

Abstract: An alginate particle containing calcium carbonate in matrix is provided to selectively release the various hydrophobic and hydrophilic physiological ingredients within the particle by releasing the relatively small amount of target material encapsulated at basic pH and the relatively large amount of target material encapsulated at acidic pH. The alginate particle contains calcium carbonate in alginate matrix, and is prepared by mixing solution or suspension containing alginate and the target material with solution or suspension containing calcium carbonate to prepare calcium carbonate-alginate mixed solution, and adding droplet of or spraying the calcium carbonate-alginate mixed solution into multivalent cation solution.

Abstract: An alginate particle containing poly(N-isopropylacrylamide) is provided to emit a relatively small amount of capture target materials below Tg of poly(N-isopropylacrylamide) and emit a relatively large amount of the capture target materials above the Tg of poly(N-isopropylacrylamide). A method for preparing an alginate particle having capture target materials comprises the following steps of: melting or dispersing capture target materials in a liquid or colloidal suspension containing a copolymer of poly(N-isopropylacrylamide) and alginate; and dropping or spraying the liquid or colloidal suspension in a solution with Ca^(2+), Mg^(2+), Al^(3+), Cr^(3+). The copolymer of poly(N-isopropylacrylamide) and alginate is prepared by reacting a NH2 group to poly(N-isopropylacrylamide) and then condensation-reacting the poly(N-isopropylacrylamide) to a carboxyl group of the alginate.
