Professor Keon Jae Lee from the Department of Materials Science and Technology (KAIST) and other South Korean scientists have developed a new way of detecting cancer. It uses a flexible, biodegradable gallium nitride (GaN) LED that detects prostate cancer.

GaNa LEDs , a high-performance light emitting device, have been commercialized in LED TVs and in the lighting industry.

So far, it is difficult to use this semiconductor material to make flexible electronic systems because of its brittleness and brittleness. However, the team has succeeded in developing a highly efficient GaN LED. Thus, this study is applicable to cancer detection using a bio-sensor with flexible LEDs.

The biometric sensor using this flexible GaN LED uses a protocol, a similar protocol for transferring thin films of GaN light LEDs into a flexible substrate, monitored by a bio-compatible packaging process. In general, the overall potential of the system for use in biomedical implant applications has been demonstrated in a clear and convincing way.

Professor John Roger from the Department of Materials Science and Engineering, UIUC, said: "Integrated biometric LEDs represent an exciting new technology, promising great potential for the purpose of excellence. Addressing the challenges and threats to human health, this study contributes greatly to the protection of human health, enabling cancer patients to have more effective options for treatment. " .
