Method for manufacturing a metal nanostructure having a chiral structure comprising regioselectivity adsorbing a peptide on the surface of a metal seed particle

A method for manufacturing a metal nanostructure, the method comprising:

• preparing a first mixture solution by mixing a metal precursor, a surfactant, and a reducing agent;
• preparing a second mixture solution by adding a peptide to the first mixture solution;
• and
• preparing a metal nanostructure having a chiral structure by adding a metal seed particle to the second mixture solution to grow the metal nanostructure,
• wherein when the metal seed particle is added to the second mixture solution in the preparing the metal nanostructure, the peptide is regioselectively adsorbed on the surface of the metal seed particle,
• wherein the metal nanostructure is synthesized at a room temperature,
• wherein the chiral structure means a structure in which the metal nanostructure does not overlap with its mirror image, and a shape which is twisted in one direction as asymmetric structure.
