  • Octachlorocyclotetraphosphazene을 사용하여 cyclotetraphosphazene 구조를 내부에 갖고 외부로 8개의 사슬 구조를 갖는 cyclotetraphosphazene 유도체를 합성하였다. 그리고 이 유도체와 콜레스테롤을 사용하여 vesicle을 형성시켰으며, TEM을 이용해서 이 vesicle의 형태를 살펴보고, encapsulation 효율 등을 알아보았다. 이 vesicle의 안정도는 dihexadecylphosphate를 첨가함에 의해서 크게 향상되었다.

  • A cyclotetraphosphazene derivative with eight chains was synthesized from octachlorocyclotetraphosphazene. The vesicles were prepared using the cyclotetraphosphazene derivative and cholesterol. The resulting vesicles were characterized by TEM and measurements of their encapsulation efficiency. The stability of the vesicles was enhanced with the addition of dihexadecylphosphate. The size and the encapsulation efficiency of the vesicles changed according to the amount of cholesterol added. The size and the encapsulation efficiency of the vesicle were lowest when the mole ratio (cholesterol: the cyclophosphazene derivative) was 0.9.
