Nanostructured materials can be designed with sophisticated features to fulfill the complex requirements of advanced material applications. In this talk, Jackie will describe the synthesis of metallic, metal oxide, semiconducting and organic nanoparticles and nanocomposites of controlled size, morphology and architecture. The nanocrystalline building blocks are used to create excellent materials for fuel cell and battery applications. Her group has also designed and functionalized nanostructured materials for drug delivery, nanomedicine, biosensor, cell culture and tissue engineering applications. The unique properties of the various nanostructured materials synthesized will be presented in this talk.
