Silver Nanoparticles Coated Zinc Oxide Nanorods Array as Superhydrophobic Substrate for the Amplified SERS Effect

One-step fabrication of SERS-active substrates based on plasmon-induced activated water, with improved activity and excellent reproducibility

“…1.6% and 8.1% for batches I and II, respectively. These extremely low RSDs were more excellent than those for liquid samples shown in the literature [39,[44][45][46]. These results suggest that the uniformity of SERS signals for probe molecules dissolved in AuNT water is indeed good.…”

Analysis on superhydrophobic silver decorated copper Oxide nanostructured thin films for SERS studies

“…Thus the diluted probe molecules in the droplet will be highly concentrated after the droplet dried on the super hydrophobic surface. This is known as the hydrophobic condensation effect [2], which may further amplify the SERS signal to achieve more sensitive detection.…”

Superhydrophobic Ag decorated ZnO nanostructured thin film as effective surface enhanced Raman scattering substrates

“…They have also shown that the Au nanoparticles distributed around the Au nanowires shows 10 times higher SERS than the dense and plain films of Au A c c e p t e d M a n u s c r i p t obtained by physical deposition. A similar work done by F. Xu [17] showed that the silver nanoparticles coated zinc oxide nanorods array can act as superhydrophobic substrates with an amplified SERS Effect. Such super hydrobhocibity is also observed in the present work.…”

“…The ZnO thin films obtained in the present study are composed of randomly arranged nanowire and have an improved hydrophobic behavior without any surface modification. The higher contact angle means the same amount of probe molecule in the droplet could be concentrated in a smaller area, and thus, increased surface coverage is obtained which is leading to the enhanced SERS signal on the substrate with high contact angle (155°) [17].
