World's Smallest 3D Bioprinter
A flexible device inspired by an elephant's trunk 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.
Researchers created and tested the device, which might one day assist physicians.
