ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(1), P. 11 - 31

Published: Jan. 2, 2024

As a promising spectroscopic technique, surface enhanced raman spectroscopy (SERS) has been intensively used in bio/chemical sensing, attributing to its unique advantages of ultrasensitive and accurate detection trace amounts analytes, high specific fingerprint-like features, fast response, noninvasive sensing. The robustness consistency SERS signals practical analytical applications highly rely on the composition, structural morphology, uniformity substrates. These factors play pivotal role determining intensity reproducibility detected signals. substrates based ordered nanostructures that are fabricated from anodic aluminum oxide (AAO)-template-assisted approaches significant interest due their cost effectiveness, scalability, precise control, exceptionally features. In this review, recent progress with sensitivity prepared AAO templates is highlighted. We emphasize optimization strategies toward achieving efficient SERS-active by fine-tuning size, morphology AAO-derived nanostructures. Furthermore, we delve into discussion flexible smart substrates, while also exploring key aspects pertinent further amplifying Overall, review aims offer insights future integration technique SERS, providing crucial perspectives for forthcoming research field.

Langmuir, Journal Year: 2024, Volume and Issue: 40(8), P. 4218 - 4227

Published: Feb. 14, 2024

Surface-enhanced Raman scattering (SERS) has emerged as a powerful surface analytical technique that amplifies signals of molecules adsorbed onto metal nanostructured surfaces. The droplet reaction method recently been employed to fabricate large-scale microring patterns silver (Ag) nanostructures on rigid substrates, which enables sensitive detection within the ring area. However, these substrates present limitations for direct on-site analyte residues irregular sample There is need develop soft and flexible SERS can intimately conform arbitrary In this study, we presented substrate using adhesive tape supporting material. This was fabricated by repeatedly transferring presynthesized Ag from tape. For model compound adenine, our exhibited good linear response 5 × 10–4 M 10–5 with low limit (LOD) 10–7 displayed enhancement factor (EF) 3.2 105. relative standard deviation (RSD) intensity achieved 1.93%, indicating its outstanding uniformity. as-prepared used in situ pesticide residue an apple dye human hair.
