METHOD OF PREPARING GOLD NANOSTRUCTURE USING THE ELECTRODLESS DISPLACEMENT PLATING METHOD

摘要

The present invention relates to a method of producing gold nanostructures using electroless plating method substitution , reduction potential than gold depositing a metal on a lower substrate to form the metal layer ; And a method for producing a gold plating solution containing gold nanostructures ions comprising the step of reacting the metal layer and provide a gold nano- structure produced by the method of manufacturing the same . The present invention is simpler and less expensive to provide an efficient method for producing a gold nanostructure advantages . Surface by using the gold nano- structure produced by the method of the present invention enhanced Raman spectroscopy (Surface-Enhanced Raman Scattering: SERS) may measure a signal or fluorescence . In addition , there is an advantage to develop an optical sensor comprising a gold nanostructure . ;
