THE METHOD FOR THE PREPARATION OF GOLD NANOSTRUCTURE USING GALVANIC DISPLACEMENT REACTION AND GOLD NANOSTRUCTURE WITH IMPROVED SURFACE ENHANCED RAMAN SCATTERING

摘要

PURPOSE: A method for manufacturing a gold nanostructure with improved surface-enhanced Raman scattering is provided to manufacture a gold nanostructure of a mushroom shape by depositing gold on a block copolymer through galvanic substitution reaction. CONSTITUTION: A method for manufacturing a gold nanostructure with improved surface-enhanced Raman scattering comprises the steps of: spin-coating PS-b-P2VP reverse micelle on a silicon wafer to manufacture a monomolecular film; treating the monomolecular film in a solvent for selectively dissolving P2VP to obtain a block copolymer template with nanopores; and performing substitution reaction of the block copolymer template to deposit gold.
