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.

“…They are based on the property that atoms and molecules have to absorb or emit energy in a certain region of the electromagnetic spectrum, which offers the information on the chemical and crystalline constitution of the sample [J. Sun et al, 2020]. When radiation is focused on a body, there may be a transition between its energy states and, depending on the region in which the incident radiation energy is located, different types of transitions occur, such as electronic transitions, which are commonly established in the ultraviolet or visible, rotational region, defined in the microwave, translational and vibratory region, the latter located in the visible, infrared or near infrared.…”

The objective of the work was to evaluate the influence of gold nanoparticles, obtained by laser ablation, on the photocatalytic action of titanium dioxide in the improvement of the physical-chemical parameters of domestic greywater, with visualization by means of a PLC. The YAG laser equipment was used for the production of spherical gold nanoparticles, whereas the Raman spectroscope allowed characterizing the different particles contained in aqueous solutions. The solar photoreactor programmable and viewable from PLC with connection to sensors allowed determining the variations of the pH, EC, DO and FCL parameters. The work consisted of a control group (greywater + titanium dioxide) and an experimental group (greywater + titanium dioxide + gold nanoparticles). The titanium dioxide doses for both groups were 0.5 mg/L and the gold nanoparticles were 0.20 ml per liter of greywater only for the control group. The experiments were carried out on sunny days with the exposure periods of 30 and 60 minutes around solar noon with an average UV index of 13.35. Once the experiments were carried out, it was determined that the pH improved by 5.30%, EC by 3.03%, DO by 29.3% and FCL by 43.71%, so that the gold nanoparticles dissolved in the aqueous solution of titanium dioxide with greywater positively influenced the improvement of the photocatalytic action of titanium dioxide in the physical-chemical parameters of greywater.

“…However, there are limited reports concerning NFT detection and none about AHD by using surface‐enhanced Raman spectroscopy (SERS) method [ 11,12 ] that is a fingerprint spectral analysis method. [ 13–21 ] For example, Wu et al [ 11 ] used raspberry‐like nanogold to detect nitrofurazone and NFT in the extract of duck meat with the limit of detection (LOD) of 50 μg/L. Zhang et al [ 12 ] detected NFT with a LOD of 14 μg/L.…”

Nitrofurantoin (NFT), a typical highly effective nitrofuran antibiotic drug, has been prohibited but still widely found in animal food products. It can be metabolized in animals to form 1‐amino‐hydantoin (AHD) that can then form stable and toxic metabolite‐protein adducts. Hence, the detection of NFT and AHD in aquatic products and feeds is very important. However, there are limited reports concerning NFT detection and none about AHD by using surface‐enhanced Raman spectroscopy (SERS) method. Herein, potassium bromide (KBr) decorated silver (Ag) nanoparticles (Ag‐BrNPs)‐based SERS approach was proposed for NFT and AHD detection. The limit of detection (LOD) for NFT was 1 μg/L. The detection of NFT residues in sea cucumber and fish feeds was also realized with the LOD of 1 and 50 ng/g, respectively. More importantly, the sensing of AHD was easily realized with the SERS approach for the first time. After the derivatization with 2‐nitrobenzaldehyde (2‐NBA), Ag‐BrNPs were also successfully utilized for AHD detection in sea cucumber with the LOD of 5 ng/g.
