Ultrasound-driven nanobubble dissipation and size characterization. (A) Schematic of the ultrasound transducer (bottom) and agarose phantom/sample location (blue). (B) Ultrasound images of crosslinked and non-crosslinked NBs before, during and after a high-power ultrasound flash cycle. (C) Dynamic light scattering intensity-weighted size distributions of crosslinked NBs before (blue) and after (red) ultrasound destruction. (D) Dynamic light scattering intensity-weighted size distributions of non-crosslinked NBs before (blue) and after (red) ultrasound destruction. Insets in panels C and D show the mean intensity-weighted hydrodynamic diameters for each group.
