"Working on creating a dust-sized particle"
Professor Moon Byung-Gi in the Department of Physics

Professor Moon Byung-Gi who has been awarded "the paper of the year" by the Korean Physical Society. He is currently working on creatiing a new dust-sized particle.
He has been  challenged to make a ’’hollow sphere’’, which is one ㎛ particle made of new material and no larger than a grain of sand. His research is focusing on figuring out how to make a hollow sphere which is the size of piece of dust and its applications.
Prof. Moom said, "chemotherapy treatment which is currently used for the patients suffering from cancer does have many drawbacks in the body. But if we could use a new particle as a transporter which can deliver cancer medicine at the treatment location, the medicine could selectively destroy cancer cells in a very effective way".   
The theory is stated as follows: step one, put medication and a nano-magnet in the empty space of the ’’hollow sphere’’ and inject it into the body. Next, transport the particle by using a magnet to the location of the cancer cells. Finally, the medication slowly comes out of the ’’hollow sphere’’ and kills the cancer cells since the sphere has a porous surface.
The main purpose of Prof. Moon’’s research is how to make this minute sphere and hollow it.
He said that based on the character of a photo-catalyst in Titanium(TiO2), he has made a significant improvement in creating a hollow sphere with a porous surface.
He also pointed out that this new material can be utilized as not only a medication transporter but also as a catalyst which can decompose an pollutant such as benzene. As a result, it can be seen that its application is unlimited.  
He has published around 70 papers in the area of Solid State Physics and Nano Physics since he started his career at PKNU. Recently, he has registered three patents including development of new LED (Light-Emitting Diode) with high efficiency and has three additional patents pending approval.
In appreciation of his achievements in the field, he was awarded "the paper of the year", on the 21th of April, in Spring academic conference held by the Korean Physical Society.
