Cancer detection from an implantable, flexible LED
Professor Keon Jae Lee A KAIST research team has developed a new type of biocompatible and bendable GaN LED biosensor. Daejeon, the Republic of Korea, August 8, 2011—Can a flexible LED conformably placed on the human heart, situated on the corrugated surface of the human brain, or rolled upon the blood vessels, diagnose or even treat various diseases? These things might be a reality in the near future. The team of Professor Keon Jae Lee (Department of Materials Science and Engineering, KAIST) has developed a new concept: a biocompatible, flexible Gallium Nitride (GaN) LED that can detect prostate cancer. GaN LED, a highly efficient light emitting device, has been commercialized in LED TVs and in the lighting industry. Until now, it has been difficult to use this semiconductor material to fabricate flexible electronic systems due to its brittleness. The research team, however, has succeeded in developing a highly efficient, flexible GaN LED and in detecting cancer using a flexible LED biosensor. 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. Professor John Roger (Department of Materials Science and Engineering, UIUC) said, “Bio-integrated LEDs represent an exciting, new technology with strong potential to address important challenges in human health. This present work represents a very nice contribution to this emerging field.” This paper was published in the online issue of Nano Energy Elsevier Journal (Editor, Prof. Zhong Lin Wang) dated September 16, 2011. Flexible GaN LED produces blue light.

KAIST Successfully Demonstrates Mobile Harbor in the Open Sea
Busan, South Korea—Large container ships are no longer required to come into ports to transport cargo, as KAIST has developed an innovative technology that will transform the paradigm of today’s cargo handling operations. A Mobile Harbor is a vessel that carries a large stabilized crane with a smart spreader and multistage trolley system, enabling the loading and unloading of ship cargo on the wavy open sea. Following a successful docking of two vessels at sea in April of this year, KAIST conducted a full scope of Mobile Harbor operations in the inner sea of Busan, South Korea, on June 29, 2011. Initiated in 2009, the Mobile Harbor (MH) is one of the university’s flagship research projects, which aims to provide a new growth engine that will lead the Korean economy to the next level of advancement, and to develop green technology through multidisciplinary and convergence research. The idea of MH came to light when thinking outside the box (why can’t a harbor go out to meet a ship on voyage and retrieve goods instead of ships coming into the harbor?) to improve problems relating to the current maritime transport system, such as port congestion, environmental issues caused by heavy sea transport, increased demand for supersized container ships, and the need for port construction and expansion. The essential technology to establish a Mobile Harbor is a docking system and crane system that can overcome the obstacles imposed by the sea, i.e., waves and wind. Connecting two operating vessels of different sizes in the unpredictable and ever-changing environment of the sea was regarded as “impossible” and had never been tried before, but, on April 26, 2011, KAIST successfully demonstrated the technology to moor vessels safely and securely. The Mobile Harbor has a unique way of mooring vessels that are anchored at sea: its flexibly designed robot arms with a square-shape vacuum suction pad at the tip reach out and attach to the hull of a container ship for docking. Each robot arm is connected to a cable and winch that further add stability to the Mobile Harbor. Foam-filled fenders are placed between the Mobile Harbor and the container ship, thereby maintaining a safe distance to prevent collisions. The crane system consists of a multistage trolley, smart spreader, and tension controller, all of which provide the crane with functionality and stability to move around cargo containers in the sea. The crane system also has various sensors like cameras and laser scanners, and therefore, it can gauge the movement of the spreader and ships as well as trace a target container in real time. As a result, the spreader, a container grabbing device, is free from the swing motions when lifting and putting down cargo and grabs a target container safely in the wavy open sea. During today’s at-sea demonstration in Busan, a research team from the KAIST Mobile Harbor Center docked a Mobile Harbor (a barge ship) right next to a container vessel (the other barge ship) and repeated freight transport operations between the two ships, presenting the great potential to commercialize the Mobile Harbor technology. The project has been implemented in collaboration with industries, research institutes, and universities in such fields as mechanical engineering, robotics, automation engineering, and ocean systems engineering. The demonstration proceeded with a wide range of participants including researchers, engineers, government officials, and entrepreneurs from Korea and around the world. Byung-Man Kwak, Director of the KAIST Mobile Harbor Center, explained his feelings on the successful demonstration: “It’s been a remarkable journey to develop a Mobile Harbor from scratch, and I’m genuinely thrilled to showcase what we have accomplished so far. Today’s demonstration of Mobile Harbor’s core technologies will really change the face of our maritime transportation system. We will be able to deliver more goods to global markets and consumers via sea route, not necessarily building more ports or expanding the existing harbors. KAIST’s Mobile Harbor will also significantly cut down the high cost related to overland transportation of cargo and in return, contribute to the reduction of carbon emission.” The Center has received much interest in possible market migration and broader application of the Mobile Harbor from businesses and organizations, e.g., US Office of Naval Research, King Fahd University of Petroleum and Minerals, Saudi Aramco, POSCO, and the Korean Navy.

Using Light to Deliver Drugs to the Brain
The cerebral blood vessels have a unique blood-brain barrier. Using this unique structure, Professor Choi Chul Hee (Department of Bio-Brain Engineering) developed a technique to deliver drugs safely to the brain using lasers to alter the diffusivity of the blood-brain barrier. The blood-brain barrier allows the entry of only those drugs related to metabolic functions which made the entry of other drugs difficult. Due to this property it was difficult to administer the drug to a patient and have it affect the patient. Therefore the question was is it possible to maintain the effectiveness of the drug and allow it to pass through the barrier? The conventional method was to actually alter the structure of the drug or drill of small hole in the head and administering the drug directly, but these methods proved to be high risk and expensive. Professor Choi’s team used an ultra-short frequency laser beam on the barrier for 1/1000th of a second on the barrier to temporarily inhibit its function thereby allowing the drug to enter the brain safely.
