Title Surface Modification of Mesoporous Silica by Alkynyl
Abstract
Combination drug therapy has become one of the dominant strategies in the clinical treatment of HIV/AIDS, diabetes, and cancer. The designation of an on-command dual-cargo release system is a hot research topic, which can realize the sustained release of two kinds of drugs. Construction of silica-cyclodextrin system meets the demand. Fabrication of alkynyl modified silica is one of the crucial issues to have cyclodextrin attached. Here, three types of alkynyl modified silica is fabricated to give the foundation of the construction of silica-cyclodextrin dual-cargo release system. The main contents are as follows: 1, Preparation of alkynyl modified silane coupling agents with different chain length in variety methods or conditions; 2, Preparation of alkynyl modified silica by high temperature synthesis; 3, Construction of silica-cyclodextrin release system. The results indicate that the drug loading rate of the system reaches 9.13% (w/w)， and the release rate 6.94% (w/w), which illuminating the successful modification of silica by alkynyl.
