Kookmin University (KMU) Prof. Yim Sang-Gyu of the Department of Applied Chemistry published an article titled “X-ray attenuation based on cancer cell imaging.” Yim’s article was published in the well-known internation- al journal Advanced Functional Materials as the 34th back cover. His article was jointly researched by a team at the Catholic Universi- ty of Korea’s Medical School and another at Harvard University’s Medical School. Imaging techniques like MRIs and CTs have difficulty in detecting small tumors when the cancer’s shape and general tissues are similar. It’s not easy to find tumors even they used the most expensive equipment in identifying small cancers. 

As an alternative of these problems, there is an active study is targeting optical imaging to observe flash signals by combining fluorescent nanoparticles with cancer cells. Yet flash signal wavelengths have a hard time penetrating human tissue — so when the cancerous cell is located deep within the body, it remains hard to detect. Yim’s research suggests a new imaging technique that strives to resolve many of these problems. Yim’s team verified the quantum dot materials that effectively block X-rays by the double capsulized for its safety for its safety. When the surface of the nanoparticle is injected with a cancerous cell target antibody, 5-millimeter tumor cells can be detected, even with a low X-ray dose. “The new concept of X-ray imaging technolo- gy which is based on blocking concept will open a new era of cancer diagnosis imaging,” said Yim. “It can help to detect the deep inside the body to detect cancer cell earlier only with the simple chest X-ray tests.”
