Outline of Final Research Achievements |
In this study, we developed a visualization method of single micro-particle behavior on an interface using a laser manipulating technique. We prepared an apparatus to manipulate and visualize an insoluble micro-particle in a single water phase using a laser manipulating technique; we developed a method to form an interface using water and silicon oil in the apparatus. We conducted the experiment using the apparatus and confirmed that a micro particle was captured by the interface. Another micro-particle was captured by an interface with small curvature but returned to the original phase after a short time. We considered that the Brownian motion of the particle itself and the curvature of the interface affect the behavior.
