| Outline of Final Research Achievements |
In theory, we theoretically predicted the use of counter waves as a method of extracting resonant light pressure, which led to experimental verification. The prediction of a novel manipulation of optical force based on nonlinear optical effects also led to experimental results. Experimentally, we established a method for precise measurement of optical force with an accuracy of about 1 fN or better. We have also succeeded in obtaining a spatial map of quantum dots with a resolution of less than 1 nm using optical force. In addition, through joint research by experts in molecular fluid dynamics and biotechnology, we precisely measured and analyzed multi-particle motion under optical force in fluids, and clarified the mechanism of motion of nanoparticles by optical force in fluids, such as the generation of a large-scale flow of surrounding particles driven by the motion of trapped particles due to scattering forces.
