A team of scientists from the United States, China, Korea and Singapore decided to create flexible ultra-thin sheets of LEDs and photodetectors that can be implanted under human skin to help perform different biomedical applications such as activating photo-sensitive drugs.

In addition the light emitting diodes and photodetectors can be used for medical monitoring.

The lead researcher of the project, which was published in Nature Materials, is John Rogers of the University of Illinois at Urbana-Champaign in the US.

According to Mr. Rogers, the part of the research that required the largest amount of time was the development of the organic LEDs (OLEDs), which are very sensitive to water and oxygen.

Researchers say that their flexible LEDs could be used to create implantable patches for monitoring wound healing. In addition, the team's latest invention could be used for making diagnosis or spectroscopy, informs Physorg.

These LEDs could also be used in robotics. Currently Rogers is working on the possible commercialization of the invention.
