Outline of Final Research Achievements

The objectives of this research are to develop high-performance paper-based devices with high analytical performance (accuracy and sensitivity) that overturn the existing concept of conventional paper-based devices as having poor analytical performance, and to establish fundamental technologies to realise the application of paper-based devices in many fields and to expand them significantly into the field of analytical chemistry. Specifically, the following research items were carried out: A: research on paper-based devices with high analytical performance (including image analysis technology); B: development of paper-based immunoassayl devices; C: development of paper-basedcell assay and cell separation devices; D: development of paper-based devices for educational tools. As a result, we succeeded in expanding paper-based devices into fields such as analytical chemistry, life sciences, and chemical education.
