Our research interests involve development of new sensing techniques based on nanomaterials such as nanoporous materials and ultrathin films for chemical and biological targets of medical and environmental interests. Additionally, we strive to understand the sensing mechanisms of such techniques and to incorporate such sensors into microfluidic devices.

Development of new analytical techniques is a central theme in all fields of the chemical and biological sciences as well as for routine medical and environmental analyses. We think key objectives of present-day analytical chemistry research are (1) miniaturization of analytical devices, (2) applications of the unique properties of nanomaterials to analytical techniques, (3) identification of biomacromolecules such as proteins and DNA, (4) single molecule detection, (5) physiologically-relevant evaluation of some chemical(s) in biological signal-transduction processes, and (6) in-vivo monitoring of biological reactions.

Among these objectives, our research is focused on developing new sensing techniques based on nanomaterials, which address the objectives (1)-(3). Nanomaterials, including nanoparticles (1-100 nm in diameter), nanopores (2- 1000 nm in pore diameter) and ultrathin films (1-1000 nm thick), are known to have unique physical and chemical characteristics that are applicable for new separation and detection principles. Their nanometer-scale size is comparable to biological macromolecules such as DNA and proteins, and thus can be used to recognize chemical and biological species with unique selectivity, and in favorable cases, to recognize individual molecular species. These features of nanomaterials can provide a means to develop unique sensing techniques that cannot be easy achieved using conventional techniques. In addition, because of their small size, sensing devices based on such materials can be easily incorporated into o=5m~nm- scale analytical devices known as microfluidic (Lab-on-a-chip) devices.

Our research involves (A) preparation of nm-scale materials (more specifically, nanoporous materials and ultrathin films), (B) characterization of the materials using various electrochemical, spectroscopic and microscopic techniques, (C) application of the nanomaterials for separation and/or detection of chemical and biological targets, (D) quantitative understanding the separation and/or detection mechanism, and (E) incorporation the nanomaterial-based sensors into microfluidic devices and application of the device for practical medical and environmental purposes. These research procedures demonstrate that our research will have an impact on many fundamental aspects of analytical, physical and material chemistry as well as on developing practical analytical devices.
