| Outline of Final Research Achievements |
A single micro droplet can be regarded as a tiny optical resonator. By utilizing the amplification of the light generated in the optical resonator, it becomes possible to detect the molecule dissolved in the droplet with high sensitivity. In this study, we succeeded in the detection of the molecule dissolved in the droplet at about 80 times sensitivity in comparison with the previously-reported equipment by using a home-built three-dimensional ion trap and microscope. In addition, it succeeded in quantitatively measuring the excitation light resonance which the excitation light irradiated to the droplet shows in wide size region. As one of the model biomembrane research, we observed the energy transfer between amphiphilic molecules which were adsorbed on the air-liquid interface in the droplet. It was found that the energy transfer proceeds efficiently in the droplet in comparison with the bulk solution.
