Combination of 2-Photon 3D-printer and bioink allows precise, direct printing of living cells Apr 16 2021 The combination of a 2-Photon 3D-printer with an innovative hydrogel-based bioink allows the direct printing of 3D structures containing living cells at both the meso- and microscale. Developed by UpNano GmbH (Vienna, Austria), the NanoOne Bio is a printer based on the successful NanoOne range of laser-powered 2-Photon 3D-printers that are able to build structures across 12 orders of magnitude. The new hydrogel has been developed with Xpect INX (Ghent, Belgium), a spin-off in foundation specialized in the development of biocompatible materials for the 3D-(bio-)printing industry. It is the only commercially available resin that allows embedding living cells straight from a culture plate within highly precise 3D-printed structures for biological applications.
