| Outline of Final Research Achievements |
Microfluidic devices have become widespread as research tools in the fields of chemistry, biology, and medicine. However, it is challenging to directly measure light absorption using absorbance spectroscopy in the small spaces. Therefore, research has been conducted on photothermal spectroscopy, which detects the heat generation followed by light absorption, while measurement of absorption spectrum was difficult. Therefore, based on the photothermal optical phase shift (POPS) detection developed by our group, we constructed an interferometer by incorporating optical fibers into a microfluidic device. Guides for optical fibers with a measurement channel were fabricated on a glass substrate using hydrofluoric acid and plasma etching. The device was verified to work as an interferometer and a photothermal signal was detected using a laser light source as a proof of principle.
