Surface Enhanced Raman Spectroscopic Investigation of PAHs at a PDMS-Au Composite Substrate†

doi:10.7503/cjcu20160553

Abstract

Abstract:

A composite surface enhanced Raman spectroscopy(SERS) substrate was fabricated through the spin coating of polydimethylsiloxane(PDMS) layer onto the Au nanoparticles monolayer film(Au MLF). This substrate exhibited the high uniformity with the derivation of SERS intensities less than 10%. Four kinds of PAHs(naphthalene, naphthalene, phenanthrene and pyrene) were employed as probe molecules to verify the performance of the composite SERS substrate. The results showed that the limit of detection(LOD) of naphthalene, anthracene, phenanthrene and pyrene detected by PDMS-Au composite substrate were 10^-6, 10^-7, 10^-8 and 10^-7 mol/L, respectively. By comparing to Au MLF substrate, the LODs were decreased by almost one order of magnitude. It was mainly originated from the physical enrichment of target molecules by the PDMS layers. Moreover, this approach opens a potential application in the identification of the mixture of PAHs.
