World's Smallest 3D Bioprinter
Researchers have created a flexible 3D bioprinter inspired by an elephant's trunk, which can deliver healing hydrogels after surgery.
Surgery is sometimes necessary to remove growths or cysts from vocal cords.
The device sports a 2.7-millimetre-wide printhead at the end of a long, flexible arm that moves like an elephant's trunk.
This innovation could help surgeons repair vocal cords.
