Abstract: Since the transfer of an SERS induced structure according to an embodiment of the disclosure uses the interfacial energy between a water surface and a thin film substructure, it is possible to perform the transfer intact without any damage to the structure. At this time, the SERS induced structure is transferred onto a non-uniform and rough surface, wherein since the transfer structure covers the surface, various types of flexible materials may be used. As a result, Raman signals and laser scattering are minimized, thereby increasing signal reproducibility, and various physical properties of a transfer target may be applied to rubbing techniques.
