New materials with reduced dimensionality, particularly molecular structures on the nanometer scale, are invaluable for their promising future use as molecular tools in investigating and engineering biologically important molecules. Our research focuses on the development and innovative use of nanomaterials such as carbon nanotubes, semiconductor nanowires, metal oxide nanorods, and polymeric nanomaterials for biomolecular and biomedical studies. This research effort will elucidate precise structure, activity, and function of biomolecules which cannot be easily measured using conventional techniques. The successful implementation of our fundamental research will be the cornerstone of creating new multiplexed, high-throughtput biosensors with unparalleled sensitivity and selectivity. It is our hope that the novel nanotools developed in our group will have a long-term impact in basic biology and clinical studies as well as in burgeoning biotechnology sectors.
Jong-in Hahm, assistant professor and Pearce Development Professor of chemical engineering, studies new materials, particularly molecular structures on the nanometer scale, for use as molecular tools in engineering and investigating biologically important systems. Ultimately our goal is to develop materials that can be applied to functions as diverse as molecular probes, improved genotyping methods, and systems for screening small molecules and early disease markers.
Our current research centers on the synthesis of materials such as nanotubes and nanowires with interesting structures and functionality. We are working to develop methods for the controllable synthesis of these one-dimensional structures on various catalysts in order to produce nanomaterials to facilitate nanoscale applications. Our group is using a variety of polymers and biomaterials to grow the nanomaterials at defined sites and with a defined geometry and orientation. While it is difficult to manipulate individual nanomaterials, our approach will overcome this difficulty by fabricating nanomaterials upon their synthesis. Our research also focuses on the development and innovative use of nanomaterials such as carbon nanotubes as well as metallic and semiconductor nanowires for biomedical studies. Materials synthesized in our group are tailored specifically for hosting individual biomolecules by controlling the chemical compositions and physical dimensions of the nanomaterials during synthesis. Materials grown this way could be used as high resolution biomolecular probes for atomic force microscopy, biomolecular electrical sensors enhanced biomolecular fluorescence detection platforms, and advanced protein/drug delivery templates.
