Safer Bioink for 3D Printed Tissues

Safe Bioink for Artificial Organ Printing
“Current hydrogel-based bioinks must go through a photocuring process to enhance the mechanical properties of the 3D scaffold after printing, with a high risk of adverse effects in the human body. In addition, there have been possibility of side effects by transplanting externally cultured cells within bioink to increase the tissue regeneration effect. Accordingly, the research team [at the Korea Institute of Science and Technology in Seoul] developed a new bioink material using a temperature-sensitive poly(organophosphazene) hydrogel, which existed in a liquid form at low temperatures and changed to a hard gel at body temperature. This enabled the regeneration of tissues only by temperature control without chemical crosslinking agents or UV irradiation and the manufacture of a three-dimensional scaffold with a physically stable structure, minimizing the possibility of immune adverse effects in the human body.” MORE
