报告内容摘要（不多于300字）：
We have developed a novel, biocompatible nonsurfactant-templating pathway to nanoporous metal oxides with high surface area (~1000 m2/g) and pore volume (~1.0 cm3/g) as well as pore size in the range of 2-15 nm with narrow pore size distribution. The nonsurfactant molecules, such as glucose, dibenzoyl tartaric acid, fructose, cyclodextrins, urea, glycerol, etc., are used as templates to direct the mesostructure formation in sol-gel reactions. The entire preparation can be performed at room temperature and neutral pH. Such a novel materials platform has enabled us to encapsulate a variety of bioactive substances including enzymes, proteins, nucleic acids and therapeutic agents directly in nanoporous host materials for biocatalysis, biosensor, drug release, nanobioreactor, and enzyme therapy applications. It also provides a new tool to study protein behavior in confined space, including protein folding and protein-protein interactions as well as protein aggregations as in Alzheimer’s and Parkinson’s diseases. The nanoporous materials have also been employed as fillers for the synthesis of nanocomposite and dental materials. In addition, electroactive polymers have been used as intelligent scaffolds for neural, cardiac and stem cell tissue engineering
