Thin Silica Shell Coated Ag Assembled Nanostructures for Expanding Generality of SERS Analytes: Simultaneous Quantitative Detection of Aniline and 4-Aminothiophenol |
| 초록 |
In this study, we demonstrated thin silica-coated and assembled Ag NPs (SiO2@Ag@SiO2 NPs) for simultaneous and quantitative detection of chemicals that have different intrinsic affinities to silver metal. These NPs were detected each SERS peak of aniline or 4-aminothiophenol from the mixture with limits of detection of 93 ppm and 54 ppb, respectively. E-field distribution based on interparticle distance was simulated using discrete dipole approximation calculation to gain insight into enhanced scattering of these thin silica coated Ag NP assemblies. These NPs were successfully applied to detect aniline in river water and tap water. Results suggest that SiO2@Ag@SiO2 NP-based SERS detection systems can be used as a simple and universal detection tool for safety. |
