If we’re going to 3D print tissues, organs, and entire body parts, scientists will have to create advanced, highly functional bioinks. Plus, these bioinks will have to withstand being printed and must survive within the harsh interior of the body.
At the Fraunhofer Institute for Interfacial Engineering and Biotechnology and University of Stuttgart in Germany, researchers are working on this goal and they’ve already developed a number of liquid bioinks that contain living cells among a mixture of other ingredients.
The new bioinks are made of biopolymers, including gelatin and hyaluronic acid, an aqueous medium,...
