What happened

3D-printed nozzle array could streamline production of drug-delivery microparticles Lisa Lock Scientific Editor Robert Egan Associate Editor MIT researchers have demonstrated a low-cost design for specialized electronic nozzles, called triaxial electrospray…

Why it matters

Triaxial electrospray emitters use electricity to precisely dispense three liquids from microscopic nozzles to generate a steady stream with three distinct fluid layers.

Common ground

The liquid forms multilayered droplets, which can solidify into layered microparticles.
