Abstract
A three-dimensional chiral nanostructure according to an embodiment of the present invention comprises: metal nanoparticles having a chiral structure: and a coating layer enclosing the metal nanoparticles. The metal nanoparticle is formed in a polyhedral structure having an R region and an S region in which atoms are arranged clockwise and counterclockwise, respectively, in the order of (111), (100), and (110) crystal faces on the basis of the chiral center, wherein at least a portion of the edges form a curve tilting and extending from the R or S region so that the metal nanoparticle has a chiral structure.
