In this study, stable gold nanoparticles (AuNPs) are fabricated for the first time on commercial ultrafine glass coverslips coated with gold thin layers (2 nm, 4 nm, 6 nm, and 8 nm) at 25 degrees C and annealed at high temperatures (350 degrees C, 450 degrees C, and 550 degrees C) on a hot plate for different periods of time. Such gold nanostructured coverslips were systematically tested via surface enhanced Raman spectroscopy (SERS) to identify their spectral performances in the presence of different concentrations of a model molecule, namely 1,2-bis-(4-pyridyl)-ethene (BPE). By using these SERS platforms, it is possible to detect BPE traces (10(-12) M) in aqueous solutions in 120 s. The stability of SERS spectra over five weeks of thiol-DNA probe (2 mu L) deposited on gold nano-structured coverslip is also reported.
