Tissue engineers face a major obstacle when creating complex 3D‑printed or implanted biological structures: there are very few ways to monitor cell health noninvasively and in real time. Existing methods often require piercing or damaging the tissue to measure metabolite
Optical Sensor Particles Allow Real‑Time Tissue Health Monitoring Using Only Light Read More »
Severe bone injuries caused by trauma, cancer, or infection often fail to heal because engineered bone tissue struggles to form the blood vessels needed to deliver oxygen and nutrients. Without vascularization, even advanced bioprinted constructs cannot mature or integrate with

Bone reconstruction remains difficult when large defects occur, because current implants often fail to match the mechanical behavior and biological complexity of natural bone. Researchers at Tampere University in Finland are working to solve this problem by developing 3D printed
Researchers at Pusan National University have developed a light activated tissue adhesive patch designed to rapidly and securely seal tears in the dura mater, the protective membrane surrounding the brain and spinal cord. Dural tears, whether accidental or intentional during

A miniature bioprinter developed by researchers at McGill University is offering a new way to reconstruct vocal cord tissue during surgery. Designed to deliver healing hydrogels directly to damaged vocal folds, the device measures just 2.7 millimeters across, making it
“We can rebuild him. We have the technology. We can make him better than he was. Better . . . stronger . . . faster.” These iconic words were part of the opening lines of the hit TV series, The
