Engineered micro-pyramids functionalized with silver nanoarrays as excellent cost-effective SERS chemosensors for multi-hazardous pollutants detection

Fabrication of Surface Enhanced Raman Spectroscopy based sensor using Ag NPs on copper tape flexible substrate

“…The SERS activities of fabricated Ag/Cu tape sensors have been analysed using both R6G and ARS (Figure 2a). One can see the selectivity of SERS analysis as both dyes show distinct fingerprint bands [24,25]. The main Raman modes such as C-C ring bending (612 cm -1 ), C-H bending (773, 1128, and 1187 cm -1 ), C-C stretching (1373 cm -1 ), C-N stretching (1449 cm -1 ), C-C stretching (1508, 1572 and 1649 cm -1 ) are observed for R6G.…”

Fabrication of sandwich structures of Ag/analyte/MoO3 sea urchins for SERS detection of methylene blue dye molecules

“…The peak intensity values in the Raman maps are comparatively lesser than that obtained in SERS spectra in (figure 8(a)) due to the lesser acquisition time chosen for Raman mapping. A crucial component in fabricating a superior SERS substrate is its stability under atmospheric conditions [62,63]. In this regard, we have checked the SERS signal stability of the Ag/MB/SUMoO 3 sandwich structures with 23 nm silver overlayer.…”

Polyacrylonitrile as a versatile matrix for gold nanoparticle-based SERS substrates

“…Therefore, the necessity for a more approachable strategy has drawn researchers to SERS. [73][74][75][76][77][78][79] Due to the distinctive ngerprints of each dye, SERS can offer excellent selectivity in complex dye mixtures. 80 Systematically analysing the results of this research will aid in the development of PAN/AuNPs composite materials for SERS applications that are highly efficient for the detection of MB.…”
