We demonstrate fabrication of higher-order three-dimensional layer stack nanostructure for molecular detection and electrode. Here, we develop two novel surface enhanced Raman scattering (SERS) platform with three-dimensional nanostructure using competitive self-assembly between convective aggregation and dielectrophoresis. Appropriate conditions are able to provide the higher-order layer stack nanostructure onto the desired area on demand. We measured the photoluminescence (PL) characters of the higher-order layer stack nanostructure. The local surface plasmon resonance is induced on the surface of the higher-order layer stack nanostructure, resulting the enhancement of PL and SERS-activity. We achieved the in situ highly sensitive SERS of analyte using the fabricated higher-order layer stack nanostructure. Our method enables the development of active functional control devices for in situ SERS and solar cell power battery.
