A superamphiphobic nozzle is prepared to manipulate tiny oil droplet. This nozzle can manipulate tiny oil droplets of varied volumes with high accuracy and reduced liquid retention due to the superantiwetting property. Accordingly, various inks with low surface tension can be printed at picoliter scale, and high-resolution 3D structures are achieved, which will be of significance for the development of liquid transportation and ink-jet printing devices.
