Summary: The development of flexible and transparent detection platforms using surface-enhanced Raman spectroscopy is highly important for in-situ, real-time analysis. In this study, soft and ultra-thin substrates composed of silver nanoparticles were fabricated for ultrasensitive detection of antibiotics. The utilization of nanotips-equipped ferroelectric templates significantly enhanced the Raman performance, resulting in excellent sensitivity, reproducibility, and uniformity.

Summary: By calcining titanium dioxide (TiO2) precursors at different temperatures, crystallized TiO2 (c-TiO2) and amorphous TiO2 (a-TiO2) nanosheets were generated for investigating the chemical enhancement of semiconductors and increasing the sensitivity of the surface-enhanced Raman spectroscopy (SERS) substrate. A two-dimensional a-TiO2/Ag nanosheet SERS substrate was successfully fabricated, and it showed highly sensitive and repeatable Raman signals compared to c-TiO2 or Ag nanoparticles alone.

Summary: Surface-enhanced Raman scattering (SERS) is an efficient technique for detecting pesticide residues, providing high sensitivity and fingerprint specificity. A flexible SERS substrate composed of cellulose fiber (CF) modified with silver nanostructures (AgNS) was developed. The substrate exhibited excellent SERS performance and was able to detect trace hazardous substances such as malathion. The characteristics of the substrate make it a potential label-free and ready-to-use sensing platform for SERS detection.

Summary: A flexible nanocomposite composed of bacterial cellulose (BC) and gold nanoparticles (AuNPs) was developed as a SERS substrate for the sensitive and rapid detection of thiram residues on apple surface. The SERS substrate showed a high enhancement factor and a good linear correlation, with a detection limit satisfying regulatory requirements. This BC-based SERS substrate demonstrated excellent analytical performance and is suitable for the quantitative analysis of pesticides on food surfaces.

Summary: In this study, nanoporous Ag nanorods were prepared through chemical reduction of electrodeposited Ag7O8NO3 nanorods using a reducing agent. The nanopores in the Ag nanorods can function as both analyte containers and SERS hot spots, providing strong SERS enhancement. The simple fabrication process and outstanding SERS performance make the nanoporous Ag nanorods promising candidates for sensitive detection of various pollutants, narcotics, and biomolecules.

Summary: In this study, a conventional silicon wafer was treated to expose terraces within the silicon nanostructures (Si-NSs) and decorated with silver nanoparticles (Ag-NPs) to enhance the surface-enhanced Raman scattering (SERS) activity. The SERS activity of Ag-NPs-decorated Si-NSs was found to be significantly enhanced compared to pristine Si-NSs. Three electromagnetic field models were developed to support experimental observations, indicating that Si-NSs facilitate light confinement and can be cascaded within different Ag-NPs-decorated terraces.

Summary: A controllable method for fabricating flexible surface-enhanced Raman scattering (SERS) substrates is demonstrated by depositing silver onto a flexible nanopillar array film. The optimized deposition process and increased nanopillar diameter and height can enhance the SERS intensity. However, high aspect ratios leading to agglomeration of the nanopillars negatively affect the SERS performance. The optimized Ag-deposited nanopillar array film exhibits excellent SERS sensitivity and signal reproducibility for application in food and biomedical analysis.
