Jinwoo Cheon is a Professor of Chemistry at Yonsei University and Head of the Nanomaterials Division of the Nano-Medical National Core Research Center of Korea. He received his B.S. and M.S. degrees in chemistry from Yonsei University in Seoul, Korea. He then moved to the University of Illinois, Urbana-Champaign where he earned his Ph.D. in organometallics and materials chemistry from Prof. G. Girolami in 1993. After receiving post-doctoral training at the University of California, Berkeley, with Prof. J. Arnold and Dr. E. Bourret in the field of molecular precursor chemistry for semiconducting materials and also at UCLA with Prof. J. Zink studying the photochemistry of inorganic materials, he joined the Korea Advanced Institute of Science and Technology (KAIST) as an assistant professor in 1998. In 2002, he moved to Yonsei University where he was appointed professor of chemistry. Professor Cheon was elected as a junior member of the Korean Academy of Science and Technology in 2003 and is a recipient of the Korean Chemical Society Award in Inorganic Chemistry (2004), the National Science Prize for Junior Faculty (2002), and the Korean Chemical Society-Wiley Young Chemist Award (2001). His research areas include the fabrication and shape control of inorganic nanocrystals, nanoscale biomagnetics, and the applications of nanocrystals for biomedical sciences.

List of current researches

1. Shape controlled synthesis of inorganic nanocrystals:
Since inorganic nanocrystals which exhibit unique shape-dependent properties will be the key component for next generation nanodevices, obtaining the ability to synthetically tune their shape is of great importance in materials and nano sciences. One of our current research interests is the shape-controlled synthesis of various inorganic nanocrystals including semiconductors, magnetic materials, and electronic materials and the understanding of nanocrystal shape-guiding mechanisms. During past few years, many structurally unprecedented shapes of nanocrystals including rods, branched rods, stars, and discs have been developed. From this research project, we are expecting to present a generalized synthetic protocol for shape-controlled nanocrystal synthesis.

2. Assembly of nanocrystals:
Once we obtain inorganic nanocrystals with various geometric motifs, the controlled assembly of nanocrystal building blocks is the next prerequisite for the realization of next generation nanodevices and nanosystems. We have been focusing on the fabrication of hierarchical superstructures of inorganic nanocrystals through chemical and biological self-assembly. Various inorganic superstructures from single-modal magnetic nanocrystal superlattices to inorganic (Au) – bio (DNA) nano-hybrid networks and NaCl structured bimodal superlattices of dual magnetic nano-components have been developed. Elucidation of new collective and synergistic properties of newly developed nanocrystal superstructures is another research theme.

3. Nanoscale bio-magnetics for biomedical applications:
Magnetic nanocrystals with unique superparamagnetism can play as key probes and vectors for next-generation biomedical diagnosis and therapy. We have been exploring the utilization of magnetic nanocrystals for high performance biomedical systems by hybridizing magnetic nanocrystals and bio-functional molecules. Precise pin-point imaging of diseases such as cancer and understanding of undiscovered molecular/cellular events will be possible through this project.
