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.

“…Dispersion of size in plasmonic particles produces a broad plasmonic spectrum that could be useful for performing SERS at different wavelengths (Mao et al, 2020). A similar effect could be also obtained with dendrites (Lu et al, 2020) or particles with a dispersion of forms (Yin et al, 2020).…”

Indirect Quantification of Glyphosate by SERS Using an Incubation Process With Hemin as the Reporter Molecule: A Contribution to Signal Amplification Mechanism

et al. 2020

The indirect determination of the most used herbicide worldwide, glyphosate, was achieved by the SERS technique using hemin chloride as the reporter molecule. An incubation process between hemin and glyphosate solutions was required to obtain a reproducible Raman signal on SERS substrates consisting of silicon decorated with Ag nanoparticles (Si-AgNPs). At 780 nm of excitation wavelength, SERS spectra from hemin solutions do not show extra bands in the presence of glyphosate. However, the hemin bands increase in intensity as a function of glyphosate concentration. This allows the quantification of the herbicide using as marker band the signal associated with the ring breathing mode of pyridine at 745 cm−1. The linear range was from 1 × 10−10 to 1 × 10−5 M and the limit of detection (LOD) was 9.59 × 10−12 M. This methodology was successfully applied to the quantification of the herbicide in honey. From Raman experiments with and without silver nanoparticles, it was possible to state that the hemin is the species responsible for the absorption in the absence or the presence of the herbicide via vinyl groups. Likewise, when the glyphosate concentration increases, a subtle increase occurs in the planar orientation of the vinyl group at position 2 in the porphyrin ring of hemin over the silver surface, favoring the reduction of the molecule. The total Raman signal of the hemin-glyphosate incubated solutions includes a maximized electromagnetic contribution by the use of the appropriate laser excitation, and chemical contributions related to charge transfer between silver and hemin, and from resonance properties of Raman scattering of hemin. Incubation of the reporter molecule with the analyte before the conjugation with the SERS substrate has not been explored before and could be extrapolated to other reporter-analyte systems that depend on a binding equilibrium process.

“…[150] Strain effects derived from structural defects, such as atomic vacancies, GBs, twinning or stacking faults, can be disclosed by HRTEM images. [151] For instance, liquid cell (LC) transmission electron microscopy (TEM) was applied on the palladium@platinum (Pd@Pt) core-shell octahedra in real-time and revealed that both the static local strain using [149] Pd atoms tend to corrode more easily on a surface under tensile strain than on one under compressive strain.…”

The increasing atmospheric CO 2 raises many associated issues, such as the rise of global mean temperature, the mass loss of polar ice sheets, and subsequent rise of global average sea level, etc. [3] As a result, there is serious motivation to capture and utilize this kind of greenhouse gas [4] and reduce reliance on fossil fuels by utilizing alternative renewable energies to achieve carbon neutrality. [5] Whilst solar and wind renewable energy sources already play an impressively increasing role in the global energy mix, energy storage systems are required to regulate this intermittent and fluctuating renewable electricity. [6] The residual or excess electrical energy from these intermittent sources can therefore be used to transform CO 2 into valuable fuels and chemicals, acting as one class of long-term energy storage. Based on these driving forces, electrocatalytic CO 2 conversion holds great promise as a future technology to store renewable energy in the long term and sequester CO 2 in the earth's carbon cycle. Generally, electrocatalytic CO 2 conversion and upgrade can take place over a wide range of temperatures and/or pressures. [7] The electrochemical CO 2 reduction reaction (CO 2 RR) at ambient temperature/pressure is considered an ideal route and offers significant opportunities to lower the global carbon footprint with wide applications. [8] CO 2 RR has become a prominent research direction, and it is of paramount importance in the electrochemical and carbon chemical industry. This approach creates a sustainable global-scale carbon-neutral economy, [9] allowing for a more innovative carbon capture and utilization (CCU) instead of carbon capture and storage. [10] CO 2 RR has many economic and environmental benefits, which includes, but is not limited to, its capability to i) reduce carbon emission by efficient utilization and conversion of CO 2 , ii) conveniently convert and store surplus intermittent renewable energies, iii) synthesize useable commercial chemicals for new applications, iv) easily regulate reaction rate/selectivity through applied voltages, and v) adapt to a wide-scale process by applications of modular electrolytic cells. [11] As an emerging part of CCU techniques, CO 2 RR provides a promising opportunity to develop new clean technologies to further tackle the issue of global warming.At its current technological state, the development of CO 2 RR is still in its infancy and faces a series of natural barriers. The Electrochemical CO 2 conversion offers an attractive route for recycling CO 2 with economic and environmental benefits, while the catalytic materials and electrode structures still require further improvements for scale-up application. Electrocatalytic surface and near-surface engineering (ESE) has great potential to advance CO 2 reduction reactions (CO 2 RR) with improved activity, selectivity, energetic efficiency, stability, and reduced overpotentials. This review initially provides a panorama of ESE effects to give a clear perspective and leverage their advantages, i...
