| Outline of Final Research Achievements |
In this research, we developed an experimental apparatus to selectively probe the surface of a single microdroplet levitated in space, and attempted to observe fluorescence excitation energy transfer occurred at the surface. First, a parallel plate ion trap was fabricated to stably levitate a single microdroplet. Microdroplets were generated using an electrospray ionization. Lasing signals from the microdroplet was observed when the droplet in which dye molecules were dissolved were irradiated with a nanosecond pulsed laser. We succeeded in observing the fluorescence excitation energy transfer between the monolayer formed on the surface of the droplet and the dissolved molecule with high sensitivity.
