Surface-enhanced Raman spectroscopy (SERS) is a powerful technique for multiplex chemical analysis. Noble metal-based SERS substrates are not only expensive, but also cannot be used for SERS detection of heat-sensitive samples such as biomolecules due to photo-thermal conversion that occurs with the irradiation of excitation light. In contrast, this phenomenon does not occur on carbon-based SERS substrates. However, conventional carbon-based SERS substrates have low manufacturing efficiency due to their complex fabrication processes and thus have not been widely used for SERS detection. In this study, we present a simple method for carbon-based SERS substrate fabrication via the carbonization of an electrospun polymer nanomesh.
