“…Three-dimensional (3D) nanostructures can greatly improve SERS sensitivity due to their large specific surface area for adsorbing more analyte molecules and a lot of hot spots along the three-dimensional structure. ,, Therefore, the development of 3D metal/semiconductor nanocomposites is an effective strategy to obtain SRES substrates with high sensitivity and recyclability. Many studies on the fabrication of 3D metal/semiconductor recyclable SERS substrates have been reported recently, including Au or Ag NPs/TiO 2 , − − Au or Ag NPs/ZnO, − Au or Ag NPs/MoS 2 , ,− ,− Au or Ag NPs/g-C 3 N 4 , − − and Au or Ag NPs/CuO and/or Cu 2 O. ,− Here, we summarize the relevant published work, involving the fabrication methods, probe molecules, and relevant parameters, as given in Table .…”

Detection of trace carbendazim in agricultural products or environment is challenging but important for human health and environmental protection. Developing a sensitive and recyclable surface-enhanced Raman scattering (SERS) substrate is one of the effective methods to detect such pesticide residues. In this work, we developed a facile method to fabricate a three-dimensional cactus-like Ag nanoparticles/CuO/Cu2O nanocomposite (CACN) based on a galvanic replacement reaction between Tollens’ reagent and Cu foam. This design combined the Raman enhancement effect and photocatalytic activity, providing a multifunctional and reusable substrate for highly sensitive SERS detection. It was found that the enhancement and photocatalysis of the CACN substrate were closely related to the concentration of Tollens’ reagent, and the 10-CACN substrate (prepared at 10 mM) demonstrated excellent sensitivity, reproducibility, and recyclability. The substrate was successfully applied for the detection of carbendazim solution with a detection limit of 1.5 × 10–10 M and could be reused up to 7 times. More importantly, the substrate can be employed for the detection of trace carbendazim in real apple peels with a detection limit of ∼8.5 × 10–4 ppm, which is far below that of 2.0 × 10–1 ppm suggested by China, United Kingdom, and European Union. These results suggest that the facile fabrication method and the excellent substrate would facilitate the SERS technology closer to practical application in the detection of pesticide residues.

“…Meanwhile, the RSDs from the unimprinted AAO samples are calculated to be 27.58% and 32.03%, respectively, and are approximately four times higher than those from the I-AAO samples (Figure S21). Therefore, compared to the previous studies, − the slot-under-groove nanoarrays demonstrate an obvious advantage as SERS substrates to achieve good signal reproducibility. Moreover, the recyclability is revealed by peeling off the slot-under-groove nanoarrays from the same I-AAO template, where the structural profile and SERS performance of the slot-under-groove nanoarrays are still comparable to the initial status after at least three repetitions (Figure S22).…”

Surface-enhanced Raman scattering (SERS) is an ultrasensitive spectroscopic technique that can identify materials and chemicals based on their inelastic light-scattering properties. In general, SERS relies on sub-10 nm nanogaps to amplify the Raman signals and achieve ultralow-concentration identification of analytes. However, largesized analytes, such as proteins and viruses, usually cannot enter these tiny nanogaps, limiting the practical applications of SERS. Herein, we demonstrate a universal SERS platform for the reliable and sensitive identification of a wide range of analytes. The key to this success is the prepared "slot-under-groove" nanoarchitecture arrays, which could realize a strongly coupled field enhancement with a large spatial mode distribution via the hybridization of gap-surface plasmons in the upper V-groove and localized surface plasmon resonance in the lower slot. Therefore, our slot-under-groove platform can simultaneously deliver high sensitivity for small-sized analytes and the identification of large-sized analytes with a large Raman gain.

“…Au decorated Ag nanocone and Ag mists decorated Au nanoassembly was reported as well that manifested a 3D distribution of SHSs and thus exhibited strong SERS enhancement. 40,46,47 Seo and his group reported lately a hybrid system consisting of a nanoparticles-nanocup array confirming the further distribution of 3D plasmon coupling that led to higher SERS enhancement. 47 It is therefore well understood that SERSactive substrates consisting of 0D, 1D and 2D nanoparticles facilitate the population of SHSs and thus effect reproducible and enhanced SERS activities.…”
