Nanoparticle Measurements by Focused-Beam Dynamic Ultrasound Scattering Method
Kana Kitao, Tomohisa Norisuye (KIT) US2022-20
Abstract (in Japanese) (See Japanese page) 
(in English) When megahertz ultrasound is incident on nanoparticles, scattering occurs, but the intensity is quite small. This problem can be solved by increasing the ultrasonic energy, but this results in acoustic streaming that inhibits particle motion. Therefore, in this study, by reducing the cell thickness from the conventional 10 mm to several hundred µm, a highly accurate dynamic nanoparticle measurement was achieved while using a powerful focus sensor. As a result, analysis of silica particles with a diameter of 30 nm became possible. Micron particle size analysis was further conducted to evaluate a wide range of particle size distributions over three orders of magnitude from 30 nm to 10 µm in diameter and compared the results with those of electron microscopy.
