| Outline of Final Research Achievements |
In this research, we conducted three projects. (1) A new method for the prolonged stable measurement of hydrogel fluorescence microsensors based on the measurement of fluorescence intensity was developed. Fluorescence recovery after photobleaching was used to compensate for the decrease in fluorescence intensity of microsensor. (2) The mass production method of the hydrogel fluorescence mcirosensor with uniformed size using a microfluidic chip was developed. Continuous fabrication of the hydrogel fluorescence microsensor of 10±0.5 um was succeeded. (3)The manipulation and cell injection of a fluorescent microsensor using multiple wavelengths of light was developed. By using this method, manipulation and injection of the microsensor into Madin-Darby canine kidney cell using 1064-nm and 808-nm lasers were succeeded.
