| Outline of Final Research Achievements |
The aim of this study was to develop a fiber-optic intravenous catheter system for continuous blood glucose concentration monitoring. We investigated materials as blood glucose sensor to be mounted on the tip of the catheter. We found anthracene-phenyl-diboronic acid was suitable as the sensor. It emitted 430 nm fluorescence with 370 nm excitation light. The intensity of the fluorescence depended on glucose concentration up to 400 mg/dl, but gradually diminished beyond 12 hours monitoring time. Anthracene-phenyl-diboronic acid was one of promising glucose sensors, but required improvement of long time sutability.
