Formation of multiple vesicles by inkjet printing. (a) Three vesicles are formed at a rate of 200 Hz, as depicted in sequential frames recorded at 5,400 frames per second (1.11, 3.33, 6.67, 9.82, 11.67, 13.70 ms) using 16 inkjet pulses per vesicle at 33 V amplitude. (b) A population of vesicles formed by high throughput inkjet printing. Scale bars are 100 μm.
