A X-ray Microscope Looking Inside of Minute Things Developed

`X-ray Microscope`, through which one can see the internal structure of a minute thing like a movie, was developed by domestic scientist for the first time in the world.

Je Jung-Ho (Department of Materials Science & Engineering.

Professor Je conducted the research with the research teams from Swiss and Taiwan, and the thesis was carried in the international science magazine `Nature` on the 9th.

This X-ray microscope can see the internal structure of a thing with some thousands times higher power magnifications than existing X-ray imaging system that can show the image in only 1mm large scale. Especially, it can successively take 200 pictures per a second that it shows the changes happening inside of body or a thing like a movie for example, peristaltic movement of minute blood vessels, anticancer drug’s killing cancer cells, and the change of internal structure of semiconductors.

The research team disclosed that plated metal has lots of defects due to the small air bubbles that are created during the process of electric gilding, which has not been known yet. The team made the microscope using powerful X-ray that is created by Pohang Radiant Ray Accelerator.

Professor Je said, “this technology can be applied to various nanotech researches including life science and new material development, as it can make us see the internal phenomena of substances, which were never known to us. ”
