제목 Simultaneous Detection of 4-Aminothiophenol and Aniline in Tap Water by using Silica-coated Silver Nanoparticle-assembled substrate
초록 Quantitative detection of specific analytes with its intrinsic surface-enhanced Raman scattering (SERS) signals were significantly affected by affinity between analytes and metal surface. In order to overcome this problem, surface of silver-assembled silica nanoparticle (SiO2@Ag NP) as SERS-active substrate was coated uniformly with thin silica shell. The silica-coated substrate (SiO2@Ag@SiO2 NP) was utilized to SERS-based simultaneous detection of aniline and 4-aminothiophenol. The limit of detection was calculated as 93 ppm and 54 ppb, respectively. Moreover, the detection process was available in river water and tap water.
