3D bioprinting inside the human body could be possible thanks to new soft robot
UNSW researchers unveil prototype device that can directly 3D print living cells onto internal organs and potentially be used as an all-in-one endoscopic surgical tool.
Engineers from UNSW Sydney have developed a miniature and flexible soft robotic arm which could be used to 3D print biomaterial directly onto organs inside a person’s body.
3D bioprinting is a process whereby biomedical parts are fabricated from so-called bioink to construct natural tissue-like structures.
Bioprinting is predominantly used for research purposes such as tissue engineering and in the development of new drugs – and normally requires the use of large 3D printing machines to produce cellular structures outside the living body.
The new research from UNSW Medical Robotics Lab, led by Dr Thanh Nho Do and his PhD student, Mai Thanh Thai, in collaboration with other researchers from UNSW including Scientia Professor Nigel Lovell, Dr Hoang-Phuong Phan, and Associate Professor Jelena Rnjak-Kovacina is detailed in a paper published in Advanced Science.
Their work has resulted in a tiny flexible 3D bioprinter that has the ability to be inserted into the body just like an endoscope and directly deliver multilayered biomaterials onto the surface of internal organs and tissues.
