Novel fluorinated polysilsesquioxane hollow spheres: synthesis and application in drug release
Autor: Sang-Wook Chu, Fuping Dong, Chang-Sik Ha, Wanping Guo
Publikováno v: Chemical communications (Cambridge, England). 46(40)
Fluorinated polysilsesquioxane (FPSQ) hollow spheres with a large empty interior were synthesized in an aqueous medium by using (trifluoropropyl)trimethoxysilane as the sole precursor. The drug release applications of these spheres were demonstrated,
