“…The dye is toxic in nature which is a menace to human beings and environment . All the obtained peaks of MB molecule (446, 502, 594, 669, 770, 860, 897, 948, 1037, 1072, 1177, 1218, 1301, 1394, 1437, and 1625 cm −1 ) matched well with the literature and suggest chemisorptions of MB on Ag nanoparticles . Sensitivity and repeatability measurements were carried out to show the potential of grown Ag nanoparticles as SERS substrate.…”

Ag nanoparticles having different size and coverage are grown on large area glass substrate (~10 cm2) using low cost successive ionic layer adsorption and reduction (SILAR) method. The SILAR parameters, such as reduction time and growth cycles are optimized to grow Ag nanoparticles with appropriate size and coverage showing maximum surface enhanced Raman scattering (SERS) enhancement of Rhodamine 6 G(R6G). For fixed growth cycles, the size and the coverage of the grown Ag nanoparticles are found to increase with the reduction time and then saturate. The size and coverage of the grown Ag nanoparticles monotonically increase with growth cycles. However, for higher growth cycles, the shape of Ag nanoparticles could not maintain their sphericity and became rock shaped/nonspherical particles, giving rise to intense quadruple plasmon resonance. The growth mechanism is proposed. Further, SERS activity of the grown Ag nanoparticles is studied for an industrial pollutant methylene blue (MB). The observed SERS enhancement factor (~109) for MB is much higher than the reported values in literature. Measured relative standard deviations values of Ag nanoparticles grown with optimum SILAR parameters suggest the excellent homogeneity and reproducibility of the SERS signal.

“…We have chosen methylene blue (MB) as a probe molecule for examining the SERS activity of Au-Cu alloy nanopods and Au-NPs as MB is widely used dye by textile, dying and pharmaceutical industries. MB is a heterocyclic aromatic compound and due to its strong hydrophilic nature, it can easily contaminate water bodies in the form of effluents which poses hazard to the environment due to its toxic and non-biodegradable nature [32,33].…”

Au-Cu alloy nanostructures have been synthesized in aqueous phase through co-reduction of HAuCl 4 .3H 2 O and CuCl 2 .2H 2 O by glucose in presence of hexadecylamine at ∼80°C. By changing the synthesis conditions, nanostructures of various shapes such as nanowires, multiply twinned tripod, tetrapod, etc were observed. Systematic variation of the synthesis condition not only leads to change in size and particle morphology but also develops various other crystallographic characters in the nanoparticles. Alloying behavior of Au-Cu has been examined through transmission electron microscope operating in its conventional and analytical modes coupled with high resolution phase contrast microscopy. These results suggested that nanostructures are composed of homogeneous Au-Cu alloy. Preferential attachment along {111} and {100} crystallographic facets of Au-Cu alloy nanoparticles led to the formation of nanowires. Multiply twinned branched shape Au-Cu (width of branch ∼30 nm) nanostructures exhibit localized surface plasmon resonance maxima in the near-infrared region. The branched shape Au-Cu alloy nanostructures display better surface enhanced Raman scattering response in the detection of methylene blue as compared to spherical Au nanoparticles.

“…Seo et al showed a Raman enhancement factor of 3.0 × 10 10 from synthesized MB‐loaded gold nanorod@SiO2 nanoparticles. Dong et al made use of a 1 × 10 −5 ‐mM solution of MB to study the modification of the surface chemistry and the enhancement mechanism of borohydride‐reduced silver particles, while Merlen et al and Li et al examined the Raman and SERRS spectra of MB on gold substrates. Mikac et al, using 633‐nm laser and MB, investigated the limit of detection for silver and gold ablated macroporous Si samples .…”

Quantitative analysis of methylene blue (MB) has been performed with Surface Enhanced Raman Scattering, SERS, using citrate reduced silver colloid activated with NaCl. In this study, the combination of SERS occurring at the proximity of the plasmon surface and of resonance Raman with excitation wavelength matched to the maximum absorbance of the molecule being analyzed, was successfully applied to maximize the Raman scattering intensity. The surface‐enhanced resonance Raman scattering (SERRS) spectra of aqueous solutions of the dye at various concentrations were collected in right‐angle scattering geometry configuration which results favorable when nanocolloidal dispersions are used. The MB concentration was correlated with the intensity of the peak centered at 1,625 cm−1 in the SERRS spectrum and this correlation resulted in an extremely sensitive quantitative investigation of the MB with limit of detection in pM level. Among others, this method can be easily applied for the examination of both the selectivity of waste water purification membranes for relevant small molecular weight contaminants or/and the solar photocatalytic effectiveness of such membranes for the degradation of pertinent pollutants by their quantitative assessment in the permeate at very low concentration range.
