“…A detailed literature survey revealed that a variety of papers were used (as a base material) for preparing the SERS substrates such as filter paper 71 , chromatography paper 72 , A4 sized paper 73 , tissue papers 74 , and different GCM grade papers 75 . The porosity of the paper (which is typically a few μm) will affect the retention of NPs on its surface.…”

This article reviews the most recent advances in the development of flexible substrates used as surface-enhanced Raman scattering (SERS) platforms for detecting several hazardous materials (e.g., explosives, pesticides, drugs, and dyes). Different flexible platforms such as papers/filter papers, fabrics, polymer nanofibers, and cellulose fibers have been investigated over the last few years and their SERS efficacies have been evaluated. We start with an introduction of the importance of hazardous materials trace detection followed by a summary of different SERS methodologies with particular attention on flexible substrates and their advantages over the nanostructures and nanoparticle-based solid/hybrid substrates. The potential of flexible SERS substrates, in conjunction with a simple portable Raman spectrometer, is the power to enable practical/on-field/point of interest applications primarily because of their low-cost and easy sampling.

“…The penetration of NPs into the paper depends on various factors such as the porosity (pore size), thickness, and hydrophobicity. 18 FP was cut into small strips (1 cm 2 ) and then soaked in the prepared NP colloids. The association of the NPs on to the paper was obvious because the color of NPs colloidal solution decreased and became colorless, which means they essentially have got transferred to the FP.…”

We present a systematic study on the fabrication, characterization of versatile, and low-cost filter paper-based surface-enhanced Raman spectroscopy (SERS) substrates loaded with salt-induced aggregated Ag/Au nanoparticles (NPs). These were demonstrated as efficient SERS substrates for the detection of multiple explosive molecules such as picric acid (5 μM), 2,4-dinitrotoluene (1 μM), and 3-nitro-1,2,4-triazol-5-one (10 μM) along with a common dye molecule (methylene blue, 5 nM). The concentrations of the dye and explosive molecules in terms of mass represent 31.98 pg, 11.45 ng, 1.82 ng, and 13.06 ng, respectively. Silver (Ag) and gold (Au) colloidal NPs were prepared by femtosecond laser (∼50 fs, 800 nm, 1 kHz) ablation of Ag/Au-target immersed in distilled water. Subsequently, the aggregated nanoparticles were achieved by mixing the pure Ag and Au NPs with different concentrations of NaCl. These aggregated NPs were characterized by UV–visible absorption and high-resolution transmission electron microscopy techniques. The SERS substrates were prepared by soaking the filter paper in aggregated NPs. The morphologies of the paper substrates were investigated using field-emission scanning electron microscopy technique. We have achieved superior enhancements with high reproducibility and sensitivity for filter paper substrates loaded with Ag/Au NPs mixed for an optimum concentration of 50 mM NaCl.

“…Unlike glass, it does not exhibit fluorescence. Although the uses of Al-foil (Martínez-Torres et al, 2015), paper (Chamuah et al, 2017), or sandpaper (Fan et al, 2014) are cost-effective as SERS substrate, they are suffering from poor stability and are too flexible to store for a long time. Periodic nanoholes on Al substrate (Lee et al, 2015) have also been employed as SERS substrate; however, it involves high cost due to the use of advanced techniques such as electron beam lithography, focused ion beam, and soft lithography (Kahraman et al, 2017).…”

“…Aluminum and copper foil (Gudun et al, 2017;Markelonis et al, 2015;Jiang et al, 2013) have the disadvantage of being too flexible, making the surface nonuniform. SERS on paper are not adequately stable, and the signal intensity decreases significantly just after a few days (Chamuah et al, 2017…”

We report herein an economically cheap and functionally stable surfaceenhanced Raman scattering (SERS) protocol of two photoactive pigments Rhodamine 6G (R6G) and Kiton Red (KR), implemented in thin films of silver (Ag) and gold (Au) nanoparticles (AgNPs and AuNPs). Both commercially available and chemically synthesized nanoparticles were used. The suitability of the nanoparticles toward SERS activity was tested through UV-visible absorption spectroscopy and scanning electron microscopy (SEM). The AgNPs and AuNPs based SERS substrates in the form of films were fabricated onto square-sized aluminum(Al) plates by simple drop deposition of colloidal nanoparticles solution onto their polished surfaces. The prepared nanoparticle films were sufficiently dried and coated further with the probe (R6G and KR) molecules by employing the identical deposition technique. The enhanced Raman signals of R6G and KR in such composite film structures were then recorded through a custom-built dispersive Raman spectrometer with He-Ne laser excitation at 632.8 nm. Our AgNPsfilm-based SERS protocol could yield the magnitude of the Raman signal enhancement up to 104 times for both R6G and KR. Moreover, AuNPs-based film was found to be less efficient toward the Raman enhancement of both compounds. Our SERS substrates can be easily fabricated, and SERS spectra are reproducible and stable, allowing one to consistently get a reproducible result even after 6 months. J. Bangladesh Acad.
