A novel SERS substrate: Wrinkled ZnS nanobelt film coated with Ag nanoparticle

Self-Assembly of Strain-Adaptable Surface-Enhanced Raman Scattering Substrate on Polydimethylsiloxane Nanowrinkles

“…We believe that the sensitivity of the SERS substrate can be further optimized by tuning the morphology of the nanowrinkles and the size of the AuNPs or by using new nanomaterials of different components and structures, such as noble metal nanoparticles 60 and Agcoated pleated ZnS nanoribbon film. 61 The uniformity and detection repeatability of the SERS substrate were investigated by using aniline (5 × 10 −3 M) as the probe. Raman signals detected at 10 random positions were collected, and the consistency and deviation of the spectral data at different positions were evaluated.…”

Periodic Arrays of 3D AuNP‐Capped VO2 Shells and Their Temperature‐Tunable SERS Performance

“…Raman signals were obtained by a confocal Raman microscope (Renishaw inVia) equipped with a × 50 objective lens (NA = 0.5) and a 532 nm laser. The enhancement factor (EF) of SERS could be calculated with the formula [ 41–43 ] where I SERS represents the Raman spectrum intensity of the R6G molecule on the SERS substrate. I bulk represents the Raman spectrum intensity of the R6G molecule without enhancement.…”

Improved SERS performance of a silver triangular nanoparticle/TiO2 nanoarray heterostructure and its application for food additive detection

“…Considering that the recognized SERS enhancement is primarily due to the intense electromagnetic field generated by the incident excitation of localized surface plasmon resonance (LSPR) of the plasmonic nano-metals and chemical enhancement from charge transfer (CT), any substrate that could improve the electromagnetic field or CT is favorable. 3,4 Coin-metal nanoparticles such as copper, 5 gold 6 and silver 7 have been widely applied in SERS studies because of their SPR effect. Among them, Ag has attracted more attention due to its strong and tunable SPR from the visible to near-infrared spectrum.…”
