Chemical Sensors Using Functional Dyes and Compact Sensing Devices

The Suzuki & Citterio Lab is working to create new sensing materials, such as dyes, and to develop chemical sensors. By combining organic molecules, electrochemistry, and molecular biology, the aim is to create chemical sensors that are smaller, simpler, and more sensitive. Such sensors will have a wide range of practical applications. Q. Our goal is to measure various substances in the environment and living organisms, which will enable us to understand many things. Primarily, were developing chemical sensors. We want to develop sensors that are useful in food analysis, healthcare, and environmental testing. So in our research overall, we develop devices that involve everything from new materials to sensors, and we work with businesses to systemize those devices further, so that theyre easy to use. In healthcare currently, MRI is the most representative imaging diagnostic method. But its still difficult to identify first-stage tumors that are less than 1 mm in size. To detect such small tumors, its necessary to develop contrasting agents that give sharper monochrome contrast than current ones, and also to selectively identify regions where tumors are present. The Suzuki & Citterio Lab is studying reactive molecules that can indicate specific regions, with the aim of developing more effective contrasting agents. Q. Were studying how to make substances in nano-particle form, or molecules that create slightly larger forms called micelles. Were also studying how to introduce …
