Progress in surface enhanced Raman scattering molecular sensing: A review

Femtosecond laser patterned silicon embedded with gold nanostars as a hybrid SERS substrate for pesticide detection

“…SERS substrates having rough surfaces with micro/nano features have found a great deal of attention in a wide range of elds and can be fabricated using numerous methods including electrochemical, lithography, electrochemical etching, laser ablation, etc. [18][19][20][21] Among those diverse approaches, ultrafast laser ablation is a versatile technique that can induce various surface patterns on solid substrates like two/three-dimensional micro/ nanostructures on diverse materials (metals, semiconductors, dielectrics, polymers, etc.). 22,23 Previously, our group has reported the fabrication of various laser-induced surface structures as well as nanoparticles (NPs) utilizing various materials.…”

Hybrid Nanostructures Based on TiO2 Nanotubes with Ag, Au, or Bimetallic Au–Ag Deposits for Surface-Enhanced Raman Scattering (SERS) Applications

“…12,13 This is due to the phenomenon of light amplification by excitation of localized surface plasmon resonances (LSPR). 1,2 Then the concentration of light occurs preferentially in crevices, depressions, edges, roughness, or sharp features on metallic particles. 2,11,13,14 Such conditions can be met by titanium oxide nanotubes, which grow perpendicular to the metal substrate, forming densely packed nanostructures.…”

Surface-enhanced Raman Scattering and Localized Surface Plasmon Resonance Detection of Aldehydes Using 4-ATP Functionalized Ag Nanorods

“…Various nanostructures of silver and gold have been utilized for SERS and LSPR studies [43][44][45][46]. The efficient use of these nanoparticles in SERS depends on the excitation wavelengths.…”
