Research Contents

We are aiming to develop future-oriented novel methodologies (new separation and detection methods) which are characterized by high-sensitivity, high-selectivity, and customization (micro-miniaturization, ultra-simplification) and have major ramifications for other academic fields. We hope to advance new techniques and research in the chemical engineering and separation engineering fields.
At present, capillary chromatography, flow injection analysis, microflow injection analysis, and micro-channel analysis are used at our laboratory as methods of absorbance, fluorescence, and chemiluminescence detection. Each of these is simple, rapid, and low-cost, and allows continuous analysis. Absorbance, fluorescence, and chemiluminescence are closely linked to one another, and so we attempt to adeptly employ experimental data on all three interactively in the establishment of new separation and detection methods.
Some of our specific research objectives are "confronting micro analysis," "development of micro-miniature analysis device 'μ-TAS' (micro-Total Analysis System)," "interpreting life and in vivo information," and "application to food- and environmental-analysis."
From an educational perspective, we believe that such study of separation and detection methods from perspectives of chemical engineering, separation engineering, and life sciences is of great benefit to students going on to become engineers or researchers in the future.
