Deep Eutectic Inks for Multiphoton 3D Laser Microprinting [data]

However, many applications demand material properties that are not accessible by conventional polymer inks. These include large stiffness, for which recent breakthroughs based on inorganic materials have been reported.

Conversely, some applications require very low stiffness and high mechanical compliance. Existing solutions achieve softness by low crosslinking densities, at the inherent expense of deteriorated spatial resolution and structure quality. Herein, we resolve this apparent contradiction by introducing multiphoton inks based on deep eutectics, comprising Lewis or Brønsted acids/bases.
