The method for the preparation of gold nanostructure using galvanic displacement reaction and gold nanostructure with improved surface enhanced Raman scattering

摘要

The present invention provides improved methods of production of gold nanostructures surface enhanced Raman scattering using a galvanic replacement reaction and accordingly relates to a gold nanostructure is made, more particularly, by spin coating the PS-b-P2VP reverse micelles in a silicon wafer to prepare a monolayer (step 1); Processing the monomolecular film prepared in step 1 with a solvent to selectively dissolve the P2VP phase and for producing a block copolymer having a nanoporous template (step 2); And provides a process for the preparation of surface enhanced Raman scattering is enhanced gold nano-structure, comprising the step (step 3) to deposit a gold producing block copolymers as a template for galvanic replacement reaction of the plating solution in the above step 2. Simple method of manufacturing method of the gold nano-structure according to the present invention does not include a dry etching process and a conventional high-temperature treatment step in the process for producing a block structure, depositing gold by the gold nano-fungal the copolymer by galvanic replacement reaction with it is possible to manufacture the gold nanostructures, useful since the plurality of the gold surface by the local electric field enhancement (hot spots), which upper portion is adjacent to or formed by a combination of nanostructures Raman scattering is enhanced, chemical, bio-materials and disease diagnostic sensor, etc. it can be used.
