| Outline of Final Research Achievements |
The target of this study is to develop ecological and economical urine sensing systems for diabetic disease screening. For this purpose, we developed a solution-gate field-effect transistor (SGFET) made of a Ta2O5/ZnO film on a glass substrate, and immobilized proton receptors, globulin aptamers, or glucose oxidase molecules on the gate electrode. These SGFET sensors were demonstrated to be able to detect the concentrations of protons, globulins, and β-D glucose in solution with enough sensitivity and detection range required for the screening. We also developed the MEMS technology to integrate these SGFETs into a healthcare chip, original ceramic gas sensors to check the characteristics of diabetic odor in urine or exhaled breath, and a prototype expert system of an electronic nose using a layered neural network.
