Professor Park Sung-ho’s Research Team Develops Self-Assembly Board with Dual Frames
Research Team of Professor Park Sung-ho (skku.edu)

Professor Park Sung-ho’s research team from the Chemistry Department at Sungkyunkwan University (SKKU) announced that they have developed a self-assembly board that can detect minute biochemistry molecules. The team created the board by combining nanoparticles and maximizing light interactions. A Surface-Enhanced Raman Spectroscopy (SERS), which uses nanoparticles such as gold and silver to concentrate rays, is a typical method for molecule detection. However, existing round or bar-type nanoparticles made it challenging to detect microscopic molecules, due to the low efficiency of the electromagnetic field. Thus, the SERS was difficult to apply commercially. To solve such inefficiencies, Park’s research team combined “dual-rim nanoframes,” which can maximize light interactions. They developed new chemical processes that formulate complex nanostructures on the surface of dual-rim nanoframes. In addition, they maximized nanoframes’ interaction with light by developing a superlattice self-assembly board. The self-assembly board contains the particles’ structural peculiarity and preserves the regularity of a large area. Furthermore, this newly developed technology can detect venomous molecules, which was impossible with existing nanoparticles. Therefore, it is expected to contribute to military science and the commercialization of spectroscopic analysis. Professor Park said, “This study proposes an area of development and methodology for SERS technology and will be applied to various fields, including biotechnology.”
