Nano bubbles are prepared by using a pressurized pump or fine ceramics in water or oil. The prepared nano bubbles are stable for more than several days. Nano emulsion (w/o type) is prepared by mixing oil, water and surfactant with homogenizer and stable more than several months. The prepared bubble and emulsion size distribution in liquid is usually measured by dynamic light scattering method. However, it is difficult to measure the particle size for smaller refractive indexes between dispersed particle and solvent by the light scattering method and small amount of particle volume. Here, the dynamical method of interactive force measurement between dispersed nano bubble and emulsion under electric field has been used to measure any kind of small particle size distribution.
