Abstract: The present invention relates to a method of preparing heavy metal nanoparticles using a heavy metal-binding protein. More specifically, relates to a method for preparing heavy metal structures, comprising the steps of: culturing a microorganism transformed with a gene encoding a heavy metal-binding protein, in a heavy metal ion-containing medium, to produce heavy metal structures in the microorganism; and collecting the produced heavy metal structures, as well as nanoparticles of heavy metal structures prepared according to said method. Unlike prior methods of preparing quantum dots by physically binding metal materials, the quantum dots disclosed herein can be efficiently produced by expressing the heavy metal-binding protein in cells.

Abstract: The present invention relates to a method for optical visualization of graphene domains, and more particularly to a method for optical visualization of graphene domains, which can optically visualize the domains and domain boundaries of graphene by forming on a substrate a graphene layer to be measured, forming a liquid crystal layer on the formed graphene layer, and then measuring the optical properties of the formed nematic liquid crystal layer. The method for optical visualization of graphene domains according to the invention uses a liquid crystal-coating method, which is simpler and easier than a conventional method for observing graphene domains. Thus, the method of the invention is simple, time-saving and inexpensive and, at the same time, enables very-large-area graphene domains to be observed with a polarizing microscope or the like. Therefore, the inventive method will be very useful in the research of graphene's properties.
