Zeta Potential Analysis of Submicron-sized Particles Using High-Energy and High-Speed Ultrasound Beam

Abstract (in Japanese) (See Japanese page) 
(in English) Zeta potential, which is a measure of stability of particle dispersion can be evaluated from electrophoretic velocity and has been measured using a microscope and the electrophoretic light scattering method. In our laboratory, we have developed the electrophoretic ultrasound scattering method which allows us to measure structures in concentrated suspensions beyond the wavelength of visible light. On the other hand, since wavelength of ultrasound is about 100 times longer than that of light, ultrasound has less sensitivity to nano- and submicron- particles. Furthermore, there was a problem that particle mobility was overestimated due to high-energy ultrasound exerted on nanoparticles. In this study, we propose a new analysis method which enables evaluation of electrophoretic velocity containing information about the direction of particle motion. Particulaly, the zeta potential of 300 nm silica particles was examined using high-energy and high-speed ultrasound pulse.
