“…However, controlling the occurrence of aggregation in the solid phase is challenging, and it has limitations in achieving uniform particle assembly due to phenomena such as the coffee-ring effect. 275,276 Researchers have addressed these issues by treating the plasmonic nanoparticles with various stabilizing agents and creating self-assembly at the water–oil two-phase interface. 277,278 An ordered assembly is achieved by combining various forces such as capillary force, electrostatic repulsion, van der Waals force, and solvation tension.…”

“…Plasmonics give rise to surface-enhanced Raman spectroscopy (SERS) mechanism by facilitating the enhancement of Raman signals. This stems from their ability to create localized electromagnetic field enhancements at the nanoscale, leading to increased scattering cross sections and, thus, contributing significantly to the amplification of the Raman signal of analyte molecules in close proximity [214,215]. In the study of Hu et al [211], the ultrathin SiO 2 shell (1 nm), served a dual purpose by effectively preventing the coalescence of Ag nanoparticle cores at elevated temperatures and functioning as a protective layer for the SERS-active nanostructure.…”

Flame spray pyrolysis (FSP) is an industrially scalable technology that enables the engineering of a wide range of metal-based nanomaterials with tailored properties nanoparticles. In the present review, we discuss the recent state-of-the-art advances in FSP technology with regard to nanostructure engineering as well as the FSP reactor setup designs. The challenges of in situ incorporation of nanoparticles into complex functional arrays are reviewed, underscoring FSP’s transformative potential in next-generation nanodevice fabrication. Key areas of focus include the integration of FSP into the technology readiness level (TRL) for nanomaterials production, the FSP process design, and recent advancements in nanodevice development. With a comprehensive overview of engineering methodologies such as the oxygen-deficient process, double-nozzle configuration, and in situ coatings deposition, this review charts the trajectory of FSP from its foundational roots to its contemporary applications in intricate nanostructure and nanodevice synthesis.

Surface-enhanced Raman scattering (SERS) spectroscopy is a powerful technology in trace analysis. However, the wide applications of SERS in practice are limited by the expensive substrate materials and the complicated preparation processes. Here we report a simple and economical galvanic-replacement-assisted synthesis route to prepare Ag nanoparticles on Cu(0) foil (nanoAg@Cu), which can be directly used as SERS substrate. The fabrication process is fast (ca. 10 min) and easily scaled up to centimeters or even larger. In addition, the morphology of the nanoAg@Cu (with Ag particles size from 30 nm to 160 nm) can be adjusted by various additives (e.g., amino-containing ligands). Finally, we show that the as-prepared nanoAg@Cu can be used for SERS characterization of two-dimensional polymers, and ca. 298 times relative enhancement of Raman intensity is achieved. This work offers a simple and economical strategy for the scalable fabrication of silver-based SERS substrate in thin film analysis.
