Prof. Lim Yeon Ho and Team Develops Cancer Diagnosis Method with a Drop of Blood

 

The research team led by Professor Lim Yeon Ho of the College of Engineering (Department of Chemical Engineering) is gaining great attention from within the academic circle with the development of the ‘nano biosensor’ that can easily diagnose cancer and easily identify the speed of its progress.

The result of the research was published in the April edition of Nano Letters (impact factor 12.2), the world’s most prestigious journal in the field of nano technology.

This result is even more meaningful since it was conducted as joint research between multiple colleges within JBNU. 

Professor Lim participated as the corresponding author, Professor Han Yoon Bong of the Department of Chemical Engineering and Professor Park Jin Ho of the College of Veterinary Medicine participated as joint main authors, and other various professors of JBNU participated in the research (co-authors were Professor Han Yoon Bong of the Department of Chemical Engineering and Professor Park Jin Ho of the College of Veterinary Medicine, and Professor Kim Dae Gon of the Medical School).

With the recent development of nano science technology, it has become possible to detect highly sensitive biochemical materials by using nano-materials. This has led to the development of future oriented portable nano biosensors that can be used at home to diagnose the real-time status of the disease.

However, one of the difficulties in doing so was that the nano-materials didn’t last long when blood was dropped onto it to diagnose diseases, which made it difficult to use for an extended period of time.

The research team created a dielectric (coating) on the nano-material with high-molecules that are polymerized at low temperature plasma to develop the technology to stably inosculate between biochemical materials and nano-materials for the first time in the world. It also successfully diagnosed cancer from the serum of a liver cancer patient.

The nano biosensor technology developed by the research team can also be used directly to diagnose other various viruses, not solely cancer.

This makes it possible to easily detect various diseases at home, as well as allowing medical institutions to monitor diseases in real-time. With such results, there are high hopes that this research result will bring about a groundbreaking turning point in the field of disease diagnosis and treatment.
