Vaporization of AuNDs.
B-mode images showing the temporal profile of the vaporization of AuNDs during exposure to ultrasound only, laser radiation only, ultrasound plus laser radiation, or AuNRs exposed to laser radiation only at 0 minutes, 1.5 minutes and 3 minutes (left, middle and right panels). The two white near-vertical linear areas in each image correspond to the walls of the tubes.
