Bioink ‘cartridges’ for versatile, personalized bioprinting

Researchers from Rutgers University (NJ, USA) have developed bioink 'cartridges' containing proteins, ligands and cells for the customized bioprinting of different tissues on demand. Biomedical engineers at Rutger's University have developed a bioink 'cartridge' system for the bioprinting of scaffolds of various human tissues. Published in Biointerphases, the team describes how the multiple cartridge system is not dissimilar to those used in typical inkjet 2D printers, whereby multiple colors are loaded and mixed to produce the desired image. Utilizing modified versions of hyaluronic acid - a natural molecule found in many human tissues - with polyethylene glycol, the team developed...
