Outline of Final Research Achievements

The patients of diabetes have been rapidly increased worldwide, and they need the accurate glycemic control using rather expensive electric glucose sensors. Therefore, the development of glucose-sensing system with low cost and simple-use is required. In this study, we focused on visual colorimetric sensing using a stimuli-responsive photonic lamellar crystals of which periodic lamellar structure can exhibit various structural colors depending on the thickness of lamellar layer. To improve a visibility of photonic crystals, lamellar films were prepared on curved surface of allayed glass-beads. We also prepared a glucose-responsive hydrogels. Then, glucose-responsive lamellar films were prepared and responsibility was optimized.
