Superamphiphobic Bionic Proboscis for Contamination‐Free Manipulation of Nano and Core–Shell Droplets

Abstract: Manipulation of nanoliter droplets is a key step for many emerging technologies including ultracompact microfluidics devices, 3D and flexible electronic printing. Despite progress, contamination-free generation and release of nanoliter droplets by compact low-cost devices remains elusive. In the present study, inspired by butterflies' minute manipulation of fluids, the authors have engineered a superamphiphobic bionic proboscis (SAP) layout that surpasses synthetic and natural designs. The authors demonstrate … Show more

“…In fact, the liquids adhesion and retention on the common nozzles are the most serious issues for many biomedical and chemical applications because they reduce the volumetric accuracy and increase the risk of cross contamination ,. To overcome the above‐mentioned problems, recently, superhydrophobic microstructures were coated onto the surface of the commercial syringe needles and could greatly improve the ability of the nozzle to dispense tiny water droplets . For example, Dong et al.…”
