Description
Summary:Incubator‐shaker method was used as a rapid technique to fabricate an efficient surface enhanced Raman scattering (SERS) substrate by combination of zero valent nanostructures and carbon fiber, which shows dramatic Raman enhancement of nitroaromatic molecule. The fabricated Ag nanoparticle on carbon‐fiber substrate (Ag–C) was used as an efficient SERS substrate to detect the adsorbed 2, 4‐dinitrotoluene molecules with a detection limit of 50 ppm. In advent, our developed SERS substrates could have great potential in detecting other nitro‐aromatic based‐explosive materials, such as 2, 4, 6‐trinitrotoluene molecules. Copyright © 2013 John Wiley & Sons, Ltd. Zero valent silver fused with a manufactured carbon‐fiber sheet referred to in this context as (Ag–C) was used as a surface enhanced Raman scattering (SERS) substrate to detect 2, 4‐dinitrotoluene (DNT), an explosive material. Essentially, the silver on the sheet served as a control group. A detection of 50 ppm was established with Raman. Thus, SERS provided results separate from those collected with blank carbon sheet alone, helping indicate the presence of DNT.
