Researchers at Columbia University's Irving Medical Center have developed a method to create three-dimensional bioengineered skin grafts. To date, bioengineered skin is typically created in flat sheets. However, these are difficult to fit to complex anatomy, such as the hand, and so these researchers have designed a more...

Columbia University scientists and collaborators at Rover Diagnostics have created a rapid PCR test that can be used at the point of care. Weighing in at two pounds, the portable device can rival the sensitivity and accuracy of traditional lab-based PCR testing equipment, but providing results in as little as 23 minutes.
The new...

Researchers at Columbia University School of Engineering and Applied Science developed an advanced organ-on-a-chip system that incorporates heart, bone, liver, and skin tissue in independent niches that are linked with simulated vascular flows. The system even includes immune cells that circulate within the simulated vasculature....

Researchers at the Columbia University School of Engineering and Applied Science have developed a new method for implanted devices to communicate with the outside world that exploits the ions that are naturally present in our tissues. Ion-rich tissues store potential energy, and in this paradigm an implanted device would alter this...

Patients with head and neck cancer frequently require surgical removal of lymph nodes from the neck. While this is necessary, it can cause pain and stiffness that can persist for a long time after surgery. Assessing neck mobility of such patients would be useful, as it would allow doctors to identify deficits in range of motion, and...
