Research Highlights: Biocompatible LEDs for Cancer Detection
Sep 19, 2011
Research group led by Professor Keon Jae Lee from The Korea Advanced Institute of Science and Technology (KAIST) has developed a biocompatible, flexible Gallium Nitride (GaN) LED that can detect prostate cancer. In the research paper published on September 16, 2011 in the online issue of Nano Energy Elsevier Journal the researchers discuss fabrication and proof of concept study usage highly efficient, flexible GaN LED in detecting cancer.
According to the report by Nanowerk.com,
Prof. Lee was involved in the first co-invention of "High Performance Flexible Single Crystal GaN" during his PhD course at the University of Illinois at Urbana-Champaign (UIUC). This flexible GaN LED biosensor utilized a similar protocol to transfer thin GaN LED films onto flexible substrates, followed by a biocompatible packaging process; the system's overall potential for use in implantable biomedical applications was demonstrated.
