From: Rapid and Sensitive SERS Detection of Bisphenol A Using Self-assembled Graphitic Substrates
(a) Raman spectra of 10−1 M BPA deposited on a graphitic sheet substrate and on a bare silicon substrate, respectively. The bottom curves are normal Raman spectra of the same substrates without BPA. The inset shows light scattering images of pure water (left) and graphitic sheet solution (right) using a 532 nm laser. (b) Concentration-dependent SERS spectra of BPA on graphitic sheets adsorbed on a silicon substrate showing a dilution series from 10−1 to 10−6 M.
