Northwestern researchers have developed a novel bio-ink material for 3D printing that holds promise for various tissue engineering and drug delivery applications. Bioprinting techniques are often limited by a dearth of bio-inks that are extrudable and able to form self-supporting gels while being biocompatible, inexpensive and allow for one-step fabrication. Prof. Shah and colleagues have addressed these issues by using a safe, biocompatible crosslinker molecule (PEG) in their formulations for their 3D biomaterials. Their novel bio-ink can accommodate living cells, opening up new avenues for tissue engineering and production of implantable medical devices. Importantly, these bio-inks begin to form gels in the printing cartridge, so there is no need for an additional gelling step after the bio-ink is dispensed. No other bio-ink formulation accomplishes simultaneous extrusion and gelation, which could make this innovative material useful in the fields of tissue engineering and drug delivery.
