    Abstract: Disclosed is an ionic liquid-coated enzyme, wherein the ionic liquid is an organic salt which presents as a liquid phase at a temperature of about 150~ C or below. The ionic liquid-coated enzyme according to the present invention remarkably improves enzyme functions, such as enantioselectivity and stability, when the enzyme which may be lipase is coated with an ionic liqui d. Further, even in the case of when the ionic liquid-coated enzyme is reused, the enantiomeric excess, enantioselectivity, and activity are not degenerate d. The coated enzyme is usable as a catalyst for providing a chiral intermediat e required in the synthesis of chiral pesticides, medicines, natural chemicals , and so on.

    Abstract: A method for preparing core/shell-structure nanoparticles is provided to be insensitive to change in a reaction condition and produce the core/shell-structure nanoparticles rapidly and reproducibly. A method for preparing core/shell-structure nanoparticles includes the steps of: (1) dissolving a shell precursor in a reaction solvent to prepare a shell precursor solution, and then stabilizing the shell precursor solution at sufficient temperature to overcoat a core surface with the shell precursor; and (2) injecting core nanoparticles into the stabilized shell precursor solution. In the step (1), the shell precursor solution is stabilized at 100-250°C. A concentration of the shell precursor in the shell precursor solution prepared in the step (1) is 0.05-1.0M.
