Fabrication of Mesoporous SiO2@CaSiO3 Hollow Spheres as Carriers for pH-sensitive Drug Delivery
文献摘要：
Hollow mesoporous silica(HM-SiO2)was prepared by the improved stober method.On this basis,HM-SiO2 was dispersed in an alkaline solution for surface etching.Meanwhile,calcium source was introduced to combine with SiO32-on the surface to form a CaSiO3 shell layer and an unprecedent SiO2@CaSiO3 sphere with a hollow double-shell structure was obtained.The as-synthesized SiO2@CaSiO3 was characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),N2-BET,IR and UV-Vis techniques,and its sustained release capacity of doxorubicin(DOX)loading was investigated.The drug loading capacity can be achieved to 0.692 mg DOX/mg SiO2@CaSiO3,exhibiting pH-responsivity under low pH conditions.
