Sillica Nanoporous Materials Adsorption And Release Study, Gang Wang

Chemistry - Dissertations

The lower efficiency of the current common ways of delivering drugs to humans like oral administration and injection make it necessary to find more efficient delivery systems. In this regard, a class of nanostructured materials called mesoporous silicates such as MCM-41, SBA-15 has attracted the attention of many scientists as drug delivery vehicles for their outstanding features like high surface area, high porosity, well-ordered, tunable nanometer pores and "non-cytotoxic" properties.

In this dissertation, comparative investigations of the adsorption capacity and drug release properties of these materials whose surfaces were functionalized with judiciously chosen organic groups via either post-grafting or co-condensation …
