“…Moreover, the XRD pattern of the constructed thin film (Figure 2B) points out the four characteristic peaks at 38.2°, 44.3°, 64.4°, and 77.6° corresponding to the (111), ( 200), (220), and (311) planes, respectively. Once the presence of FCC lattice planes characterized by silver element is noted, we claim that Ag NPs-DES is successfully synthesized [37], and the novel procedure is rudimentarily valuable in Ag NPs fabrication. The development of clusters into nanoparticles following our strategy is supported by DES.…”

Deep eutectic solvents (DESs) have been well-known lately because of their exceptional thermal stability, polarity, and environmental friendliness. There have been numerous advancements in silver nanoparticles (Ag NPs) fabrication, but no attention to the potential of DES in Ag NPs synthesis is considered and studied carefully. In this study, we present a novel strategy using a selected DES to fabricate Ag NPs in which AgNO3 is chemically reduced by L-ascorbic acid. The results adapted from characterization methods demonstrate that Ag NPs are successfully fabricated, which are further used for the construction of the surface-enhanced Raman scattering (SERS) substrate. The two analytes chosen for SERS quantitation are nitrofurantoin (NFT) and sulfadiazine (SDZ), which throughout the SERS technology, their residues can be traced at 10-8 M for both NFT and SDZ. The highest enhancement factors (EFs) are competitive, 6.29Ï107 and 1.69Ï107 for NFT and SDZ, respectively. Besides, the linearity coefficients are extremely close to 1 in the range of 10-8 M to 10-3 M of concentration, and the SERS substrate shows attentional uniformity along with great selectivity. These powerful SERS performances coherently indicate that DESs have tremendous potential in nanomaterials fabrication applied for biosensors’ substrate construction.

“…[53] The OH-modified glass surface, on the other hand, was studied in the transformation to the functional group amine (À NH 2 ) by 3-aminopropyltriethoxysilane. [78,79] After 2 hours of soaking, [53,80] the Ag NP coating on the modified glass was immersed for 1 hour in ZIF-8 to generate the Ag/ZIF-8 structure, which is a reversed arrangement structure and shown in Figure 6.…”

Stacking‐order Reversed Multilayers of ZIF‐8 and Silver Nanoparticles for the SERS Detection of Organic Dye Species

Surface‐enhanced Raman spectroscopy (SERS)‐active generally using include nanosized noble metals, semiconductors, or their combination, all of which are mostly subject to challenges such as difficulty in controlling fabrication processes, chemical stability of sensor substrates, reproducibility of amplified Raman signals. To address these concerns, novel SERS substrates were produced by combining zeolitic imidazolate framework‐8 (ZIF‐8) and Ag nanoparticles into stacked layers where the ZIF‐8 acted as “trap nets” of the reporter molecules (organic toxins, rhodamine B, methylene blue and crystal violet). Two different multilayers on a glass slide generated by reversing the stacking order, i. e., Ag/ZIF‐8/glass and ZIF‐8/Ag/glass produced different SERS results. The ZIF‐8/Ag/glass multilayer demonstrated a higher enhancement factor (∼1013), the lower limit of detection (∼10−14 M) of rhodamine B, with a relative standard deviation of 4.2% for crystal violet, which was 10 times greater than the former arrangement. The sensitivity of the SERS substrates via exposure to low concentrations of organic dyes species was measured. Structural, surface morphology and optical features of the substrates were further examined. This result can pave the way for the development of metal‐organic framework‐based SERS platform and provide new insights into its application for label‐free sensors in biomedical diagnosis and environmental monitoring.

“…23 Chemical deposition provides the advantages of low time cost, in situ growth on material surfaces, and more adjustable shape and thickness. 24,25 However, the use of a programmable chemical self-assembly MOF layer on the SERS sensor substrate for constructing a highly selective, sensitive, and repeatable sensor for the detection of organic dye has not yet been studied.…”
