Nanoparticle & Core-Shell Nanoparticle
The properties of nanomaterials whose sizes are only a few billionths of a meter have unique properties that are neither bulk nor molecular and can be tuned via the size, shape, and structure of the materials. We are interested in the synthesis and self-assembly of inorganic and core-shell nanoparticles having new structures. By introducing multifunctional organic, organometallic, or biological groups into such nanostructured materials, we create new classes of nanomaterials with unprecedented and potentially useful properties for nanoelectronics, sensing, biological imaging, and targeted drug delivery.
Porous Materials for Drug Delivery
The bottom-up synthesis of nanostructured and mesoporous materials using templates can create various new classes of nanomaterials. Our research in this area focuses on the combination of "hard templates" with "self-assembly" to produce multifunctional nanoporous and mesoporous nanospheres. Using these materials, we investigate host-guest inclusion, immobilization of enzymes for biocatalysis, and adsorption and delivery of anti-cancer drugs and chemical species.
