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.

“…To demonstrate this feasibility, two frequently utilized laser sources (532 and 785 nm) for SERS measurements were applied to detect trans‐1,2‐bis‐(4‐pyridyl) ethylene (BPE). [ 81 ] As shown in Figure 6a(ii), intrinsic SERS spectra for 100 × 10 −6 m BPE were measured on the Au–Ag@ZIF‐67‐CO using both laser sources. As a control, identical measurements were also conducted on the Si‐wafer substrate, and no noticeable Raman peaks were observed (Figure S15, Supporting Information).…”

Here the use of heterometallic interfaces on metal–organic framework‐derived structures as surface‐enhanced Raman scattering (SERS)‐active substrates is investigated for sensitive and homogeneous SERS detection. Zeolitic imidazole framework‐67 (ZIF‐67) is grown on a conductive glass substrate via chemical bath deposition, followed by carbonization and oxidation to form ZIF‐67‐derived Co3O4 (ZIF‐67‐CO). For the sensitive and homogeneous SERS analysis, ZIF‐67‐CO is converted to the heterometallic interface Au–Ag@ZIF‐67‐derived Co3O4 (denoted as Au–Ag@ZIF‐67‐CO) via electrodeposition and successive chemical grafting. The optical properties of Au–Ag@ZIF‐67‐CO indicate a uniform and large‐scale distribution of both metals on the surface. Raman signals from the substrate are evenly enhanced based on the Raman intensity and shift mapping over a large area. Due to the multiple absorption bands of the Au–Ag@ZIF‐67‐CO substrate, signal enhancement can also be achieved with two different laser sources (532 and 785 nm) that are frequently used in SERS. As a result, concentration‐dependent and fingerprint SERS signals of small molecules such as 1,2‐bis‐(4‐pyridyl) ethylene, Nile blue A, and 1,1′‐diethyl‐2,2′‐cyanine iodide are obtained, and their signal enhancement factors are 104–105. Collectively, the use of heterometallic‐interfaced ZIF‐67‐CO will be a beneficial approach for collecting reproducible SERS signals of various target analytes.

“…Formed structures were tested as SERS substrates using Raman spectrometer Alpha 300R (WITec, Ulm, Germany) equipped with 532 nm laser and 10×/0.25 objective (~3 μm collection spot). We chose 1,2-di(4-pyridyl)ethylene (BPE, Sigma-Aldrich Co., St. Louis, MO, USA) as a probe molecule, which is commonly used in case of 532 nm excitation because of its non-resonant behavior [ 26 , 27 ]. The spectra were collected in the center of the dried droplet (4 μL) of BPE water solution (10 −4 M) along the laser-irradiated lines on the glass.…”

SERS-Active Pattern in Silver-Ion-Exchanged Glass Drawn by Infrared Nanosecond Laser

et al. 2020

The irradiation of silver-to-sodium ion-exchanged glass with 1.06-μm nanosecond laser pulses of mJ-range energy results in the formation of silver nanoparticles under the glass surface. Following chemical removal of ~25-nm glass layer reveals a pattern of nanoparticles capable of surface enhancement of Raman scattering (SERS). The pattern formed when laser pulses are more than half-overlapped provides up to ~105 enhancement and uniform SERS signal distribution, while the decrease of the pulse overlap results in an order of magnitude higher but less uniform enhancement.
