Smart bioink shields delicate neural cells during precision 3D printing
3D bioprinting allows scientists to build custom tissue structures for medicine, but printing soft tissues like the human brain remains a major challenge.
AI Summary
3D bioprinting allows scientists to build custom tissue structures for medicine, but printing soft tissues like the human brain remains a major challenge. The strong pushing forces required to squeeze biological materials through tiny printer nozzles often crush and damage sensitive cells, leading to low survival rates and weak printed structures.
