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.

- Claim:
1. A method for transferring an SERS induced structure, the method comprising: forming a water-soluble thin film on a substrate; manufacturing a surface-enhanced Raman scattering (SERS) induced structure on the water-soluble thin film; separating the SERS induced structure from the substrate through capillary separation; and transferring the separated SERS induced structure onto a flexible material through the capillary force of water;
- Claim:
2. The method of claim 1, wherein a water-soluble material forming the water-soluble thin film is selected from the group consisting of polyvinyl alcohol, polyethylene glycol, dextran, polyvinylpyrrolidone, carboxymethylcellulose, salmon DNA, sodium chloride, ammonium sulfate, or ammonium persulfate.
- Claim:
3. The method of claim 1, wherein the thickness of the water-soluble thin film is 10 nm to 100 nm.

4. The method of claim 1, wherein the manufacturing of the SERS induced structure comprises manufacturing a metal nanostructure or manufacturing a polymer thin film-based structure.
- Claim:
5. The method of claim 1, wherein in the separating of the SERS induced structure, the SERS induced structure, water-soluble thin film, and substrate are simultaneously immersed in water and the substrate is placed into the water at a slower rate than the separation rate of the water-soluble thin film.
- Claim:
6. The method of claim 1, wherein in the separating of the SERS induced structure, the moment the SERS induced structure, water-soluble thin film, and substrate touch water, the water-soluble thin film is dissolved and the SERS induced structure is separated from the substrate.
- Claim:
7. The method of claim 1, wherein the separated SERS induced structure is a self-supporting structure that floats on a water surface based on the surface energy of water.
