Outline of Final Research Achievements

We proposed and proceeded the experiment to find the optimized the microcavity to realize the living cell laser oscillation. Experiments were performed using liposomes to incorporate green fluorescent particles inside the microresonator. Liposomes are closed vesicles composed of lipid bilayers, and have been used as biomembrane models. A liposome is a capsule that can be produced in water by using phospholipid, which is a constituent component of a cell membrane or a biological membrane. It has also been experimentally shown that cells with various shapes of cells grow by the remodeling of cells encapsulating cytoskeletal proteins in liposomes. Furthermore, we have found that it is suitable for a microcavity biomedical laser because it can contain green fluorescent protein inside. The liposomes were irradiated with a wavelength 488 nm laser to measure green fluorescence from liposome pseudo cells.

Academic Significance and Societal Importance of the Research Achievements

生体細胞を用いた生体レーザ研究は挑戦的でまだその実証例が十分になされていないことにより更なる実験と計算が必要であるが、リポソームが微小共振器を構成する微小球として有望な候補であることを見出した。さらにリポソームを用いた緑色蛍光測定を行ったことから今後の最適化により生体レーザ発振実験へと展開可能であることも見出した。実験再開できる時期までは計算等を主体に行い将来へと発展させる。
