Can a flexible LED placed on the human heart, brain, or blood vessels diagnose or even treat various diseases? New research suggests these possibilities may soon become a reality.

A team of researchers in South Korea led by Prof. Keon Jae Lee (Department of Materials Science and Engineering, KAIST) has developed a new concept in cancer detection: a biocompatible, flexible gallium nitride (GaN) LED that can detect prostate cancer.

GaN LED, a highly efficient light emitting device, has been commercialized in LED TVs and in the lighting industry. Until now, it has been difficult to use this semiconductor material to fabricate flexible electronic systems due to its brittleness. The research team, however, has succeeded in developing a highly efficient, flexible GaN LED and in detecting cancer using a flexible LED biosensor.
