A Novel Ultrasonic Method for Characterizing Suspensions of Nanoparticles

Abstract
The UltraSonic Pulsed Doppler (USPD) technique is a novel ultrasonic-backscatter technique for characterizing nanoparticles. Using a single transducer and able to operate in almost arbitrary vessels on samples over a range of concentrations and opacities, the system can measure concentration, size (with precision exceeding that of DLS) and mechanical compliance (for particle functionalization monitoring). To date, the system has ‘imaged’ dendrimers, colloids, carbon nanotubes, polymer beads and protein.
