Investigation of 1D Siliver Nanoparticle Arrays for Use as Molecule Concentration-Specific SERS Substrates

Figure 3

Raman spectra of BPE molecules adsorbed onto two different substrates. (A) 2×10⁻⁶ M of BPE solution drop casted on the SBS template surface uniformly distributed with Ag nanoparticle chains. (B) 2×10⁻⁶ M of BPE solution drop casted on pure silica glass surface. For spectrum (A) and (B), 100 μW laser power was used. (C) 2×10⁻³ M of BPE solution drop casted on pure silica glass, 1 mW laser power was used. Spectrum (C) was magnified 120 times for clarity.
