Our research interests involve development of new separation and sensing techniques based on nanostructured materials for chemical and biological targets of medical and environmental interests. In addition, we strive to establish novel methods for fabrication of self-organized, nanostructured materials of controlled morphologies and chemical properties, and to understand the separation/sensing mechanisms within such nanostructured materials at the molecular level.We are mainly interested in materials comprising nanostructured molecular pathways such as nanopores and nanodomains with dimensions close to molecular and ionic sizes. Such materials have been employed in numerous applications relevant to medical and energy sciences on the basis of their unique permeability based on enhanced steric, electrostatic and chemical interactions within the confined spaces. Our research goals are to understand molecular-level mechanisms behind the unique permeability of nanospaces, and to develop highly efficient separation/sensing media based on the fundamental understanding of molecular penetration through the nanostructures. Ultimately, we will pursue incorporating nanostructured separation/sensing media into µm~nm-scale analytical devices known as microfluidic devices.
