Career
Hyeon is a leading scientist in the area of synthesis, assembly, and biomedical applications of uniform-sized nanoparticles. In particular, his research group developed a new generalized synthetic procedure, called as “heat-up process”, to produce uniform-sized nanoparticles of many transition metals and oxides without a size selection process (see review articles in "Chemical synthesis of magnetic nanoparticles," Chem. Comm. 2003, 927, “Synthesis of Monodisperse Spherical Nanocrystals,” Angew. Chem. Int. Ed. 2007, 46, 4630, and “Colloidal Chemical Synthesis and Formation Kinetics of Uniform-sized Nanocrystals of Metals, Oxides, and Chalcogenides,” Acc. Chem. Res. 2008, 41, 1696). The synthesized nanoparticles include metals (Fe, Cr, Cu, Ni, Pd, and Ni/Pd core/shell), and metal oxides (γ-Fe2O3, Fe3O4, CoFe2O4, MnFe2O4, NiO, and MnO). Using the heat-up process, large-scale (10s of grams) synthesis of monodisperse nanocrystals of magnetiteMagnetite
