Researchers have demonstrated that LEDs can be a new weapon against prostate cancer.
In light of its viability as a replacement for soon-to-be-phased-out incandescent light bulbs, LEDs have become a controversial and much politicized area of innovation. It's kind of a shame because beyond the contentious debates, the technology has the potential to revolutionize critical aspects of our day-to-day lives, such as health care.
The latest example of its game-changing application comes from researchers at the Korea Advanced Institute of Science and Technology, who recently demonstrated that a special type of flexible LED can, for instance, be surgically implanted unobtrusively inside the human body to detect cancer and possibly treat diseases.
The new concept, called GaN LED, is a highly efficient light emitting device that can be found in LED TVs and various lighting products. Until recently, it had been difficult to incorporate this semiconductor material into flexible electronic systems due to its brittleness. GaN LED is not only flexible, but also features a flexible LED biosensor to catch the appearance of prostate cancer cells.

Keon Jae Lee, a materials science and engineering professor, first hit upon the idea with his co-invention of "High Performance Flexible Single Crystal GaN," developed during his PhD course at the University of Illinois at Urbana-Champaign (UIUC). His flexible GaN LED biosensor utilizes a similar method to transfer thin GaN LED films onto flexible substrates. This is followed up with a biocompatible packaging process that enables the technology to be used for implantable biomedical applications.
"Bio-integrated LEDs represent an exciting, new technology with strong potential to address important challenges in human health," said Professor John Roger. "This present work represents a very nice contribution to this emerging field."

This article describes the LED technology but no information related to HOW this can detect cancer! Yes, it can be implanted- but then what? For instance, how is it monitored externally? Is it viewed by doctors periodically? It seems to give the impression that the patient's prostate will start to glow indicating growth of cancer... Please try to give a complete description of the technology- and its application- and avoid misleading titles?
Due to applied funding and the work accomplished during my lifetime, new innovations that could save my life keep being announced. Problem is, not only will most of them never make it to the marketplace, but the FDA will block them at every chance. Since I am getting older, and wiser... I have decided to stop developing technologies that can save lives and instead switch to lethal weapons systems, so at the least I can spend my final years drinking beverages on some untarnished beach while the rest of the world continues to either whittle away their time to fruitless behaviors, or block that which they simply do not care to understand, or acknowledge as useful. Whatever. Nice cancer detection concept, by the way.
Please get a human editor to read these before posting. "Its" and "It's" are not interchangeable, dammit.
