Chang Ji-han and Lee Jae-kyeong, led by Prof. Kang Tae-wook,

Develop Technology for Manufacturing Easy Nano-sensor, Utilizing Capillary Phenomenon

 

 

Chang Ji-han, a graduate school course researcher, and Lee Jae-kyeong, an undergraduate student, at the Chemical and Biomolecular Engineering Department of Sogang, developed a technology to freely apply a nano-sensor to the surface of various products in order to identify drugs, explosive materials, hazardous food, and counterfeit money, in collaboration with Prof. Heo Dong-eun at the University of Pennsylvania in the U.S. The study was conducted with Jang Ji-han as the primary author and Lee Jae-kyeong as co-author and was published in the online edition of Nano Letters, an international journal on nano science, on February 20.

 

The optical metal sensor on a nano-meter scale is expected to drastically improve the speed and sensitivity of molecular detection technology and will be used to replace the existing hazardous gas sensors. Merely using relatively cheap and popular glass capillaries without depending on high-cost manufacturing facilities and complicated processes, the team developed a technology to manufacture high-sensitive metal nano-sensors that can be used on any product surface. It is projected that this could be applied to fields in which fast examination is required, such as food safety evaluation, drug testing, explosive material detection, and counterfeit money identification.

The study was sponsored by the project for hub research centers and medium-sized studies and the C1 gas refinery project by the Ministry of Science and ICT-the National Research Foundation.
