Schematic representations of a segmented droplet injection, b piezo droplet injection, and c acoustic droplet injection, adapted and reprinted from Echelmeier et al.4. Corresponding experimental images of d the segmented droplet generation in oil with a protein crystal (needle-shaped) containing droplet, e piezo-actuated droplet formation, and f an acoustic droplet ejection (ADE) injector. Adapted and reprinted from Sonker et al.70, Doppler et al.80, and reprinted with permission from Roessler et al.177 and Mafune et al.147.
