Students Develop Scaffold-Free Bioprinting Technology

A team formed from students at Ludwig-Maximilian University of Munich and the Technical University of Munich has developed what they hope will be a breakthrough in bioprinting. Team biotINK, formed for the International Genetically Engineered Machine Competition (iGEM), didn't even require special machinery for their biotINK printing process - just a simple Ultimaker 2+ 3D printer that they modified by replacing the extruder with a 3D printed syringe pump and programming it to extrude cells with millimeter-level precision. The bio-ink, which is capable of printing tissue without the need for a scaffold, was devised by combining biotin, also known as vitamin B7, with streptavidin, a protein naturally attracted to biotin molecules that acts as a super-strong binding agent.
