Single-walled carbon nanotube based SERS substrate with single molecule sensitivity

In single molecule study, surface-enhanced Raman scattering (SERS) has the advantage of specifically providing structural information of the molecules targeted. The main challenge in single molecule SERS is developing reusable plasmonic substrates that ensures single molecule sensitivity and acquires intrinsic information of molecules. Here, we proposed a strategy to utilize single-walled carbon nanotubes (SWNTs) to construct SERS substrates....
