. At Illinois Hyeon studied sonochemical synthesis of nanostructured catalytic and magnetic materials. From June 1996 to July 1997, he was a postdoctoral research associate in the Wolfgang M. H. Sachtler group at Northwestern University. He joined the faculty of the School of Chemical and Biological Engineering at Seoul National University in 1997.

Career

Hyeon is a leading scientist in the area of synthesis, assembly, and biomedical applications of uniformly sized

nanoparticles A nanoparticle or ultrafine particle is usually defined as a particle of matter that is between 1 and 100 nanometres (nm) in diameter. The term is sometimes used for larger particles, up to 500 nm, or fibers and tubes that are less than 1 ...

. In particular, his research group developed a new generalized synthetic strategy, called “heat-up process”, for producing uniform-sized

of many

transition metals In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded. They are the elements that can ...

and oxides without a size selection process. With this simple and inexpensive method, his group went on to design and fabricate multifunctional nanostructured materials for biomedical applications. Hyeon developed a new T1 MRI contrast agent using biocompatible manganese oxide (MnO) nanoparticles, exhibiting detailed anatomic structures of mouse brain. His group reported on the fabrication of monodisperse magnetite

immobilized with uniform pore-sized mesoporous silica spheres for simultaneous MRI, fluorescence imaging, and drug delivery. The first demonstration of high-resolution in vivo three-photon imaging using biocompatible and bright Mn²⁺ doped ZnS nanocrystals was published in 2013. Uniformly sized iron oxide nanoclusters could be successfully used as T1 MR contrast agent for high-resolution MR angiography of macaque monkeys. His research interests also includes engineering the architecture of nanomaterials and utilizing them in lithium ion battery, fuel cell electrocatalysts, solar cells, and thermoelectrics. The group reported in 2013 the first demonstration of galvanic replacement reactions in metal oxide nanocrystals, and were able to synthesize hollow nanocrystals of various multimetallic oxides including Mn₃O₄/γ-Fe₂O₃.
