Fancy having a foreign body within your own that would be say, for your own good? That’s right, it seems as though cancer will soon be able to be detected early thanks to an implantable, flexible LED. This particular LED will be placed on the human heart itself – oh, I shudder to think of the procedure required to do so, not to mention the kind of skill that the surgeon needs to have? Not only that, this very same LED can also be placed on other parts of the body (implanted) as well to diagnose, and perhaps even treat various diseases.
This concept is still being improved by a team that comprises of Professor Keon Jae Lee (Department of Materials Science and Engineering, KAIST) and his crew, where they managed to work on a biocompatible, flexible Gallium Nitride (GaN) LED that can detect prostate cancer.
GaN LED is a highly efficient light emitting device which saw commercialization efforts in LED TVs and in the lighting industry, and it is interesting to note that such LEDs can now be used in an effort to save human lives thanks to early detection of cancer. Good luck, guys, we hope you will be successful in your endeavor!
