Preparation of vesicles using octasubstituted cyclotetraphosphazene

Abstract

A cyclotetraphosphazene derivative having eight chains was synthesized from octachlorocyclotetraphosphazene, which was employed along with cholesterol for the preparation of vesicles. The resulting vesicles were characterized by TEM and encapsulation efficiency. The stability of the vesicles was enhanced in the presence of dihexadecylphosphate.
