“…As can be seen, obvious SERS signal of CV is only obtained from AgNPs as substrate (Fig. 4a) [26]. Besides, all Raman signal to noise ratios obtained on GO-Ag are much lower than that obtained from AgNPs.…”

“…Here, the GO-Ag 2.4 /5 as optimized above was used as SERS substrate to test its SERS response to several aromatic dyes MG, MB, CV and R6G with concentration from 10 -5 M to 10 -7 M. As can be seen in Fig. 8, aromatic dyes with 10 -5 M display obvious characteristic peaks for each corresponding dyes with strong signal intensity and high signal to noise ratio [24][25][26]. For dye molecules at 10 -6 M, some vibration peaks of dyes are still be distinguished; for 10 -7 M dye molecule, only background signal from GO are observed.…”

“…Besides, 2D nanostructured materials deposited with noble metal NPs, such as anodic aluminum oxide layer, polymer thin films, filter paper, and porous silicon layer, are also prepared as SERS substrates. Furthermore, 3D porous structures embedded with Ag or Au NPs have also been exploited as efficient SERS substrate, such as porous polymers, porous silicon, porous alumina membranes and ceramics, and porous glass ceramics . Compared with colloid and 2D SERS substrate, it is recognized that 3D substrate can provide 3D spatial structure and larger specific surface area (SSA) for fast permeation and binding of more target analytes to form more hot spots within the laser‐illumination area, resulting in better SERS performance .…”

Porous alumina aerogel synthesized by sol–gel method was used as facile and sensitive surface‐enhanced Raman scattering (SERS) platform. In a simple “drop‐test” SERS detection, low concentration dye solution mixed with silver nanoparticles was directly dropped on the surface of aerogel platform for SERS detection immediately. The pore structure of alumina aerogel was tuned by adding PEG‐400 and varying the gelation temperature. The effects of surface morphology and pore size of alumina aerogel platform on SERS performance of crystal violet (CV) were investigated. The result shows that large specific surface area and interconnected pore network of aerogel are helpful for fast permeation of solution, generation of “hot spots,” and adsorption of probe molecules. The Raman signal of CV was largely enhanced, enabling a detection concentration to 5 × 10−10 M with a SERS enhancement factor of 3.4 × 107. The SERS enhancement of alumina aerogel platform is remarkably improved with the increase of specific surface area and pore size, which is also confirmed by the finite‐difference time‐domain simulation. Moreover, the relative standard deviation of SERS intensity at 1619 cm-1 band for 5 × 10−8 M CV on aerogel platform is about 12%, indicating a good reproducibility.
