Microscopy images of HUVEC cells incubated with targeted DFB droplet samples A) before exposure to a vaporization pulse delivered from a diagnostic ultrasound machine and B) after vaporization. Before vaporization, large outlier droplets are visible, while nanodroplets are not optically resolvable. Post-vaporization, a high number of small bubbles on the order of 1 – 3 µm can be seen adhering to the cell plane. Large bubbles were also visible in some microscope images that were likely a result of vaporization of outlier droplets, or a result of coalescence due to repeat pulsing of smaller formed bubbles.
