Research summary
Dynamic Light Scattering (DLS), which detects fluctuation of scattered light, is the widely-used method to measure the size or stability of nano particles dispersed in fluid.
However, it cannot be used for highly turbid suspensions since the light does not transmit.
Associate Prof. Norisuye applies Dynamic Ultrasound Scattering (DSS), which utilizes ultrasound instead of light, to highly turbid suspensions, and lowers the detection limit from micron-order to tens of nano meters.
By splitting the ultrasound into many frequencies, dynamic structure of samples can be analyzed.
This method is expected to be applied to the analysis of the structure and stability of turbid samples such as ink, slurry, or functional gel materials.
