제목 Thin silica shell coating of SERS-active nanostructure enhancing adsorption capacity for non-thiol analyte
초록 Silver nanoparticle-embedded silica nanoparticle (SiO2@Ag) as SERS substrate was coated with thin silica layer to enhance adsorption capacity for different analyte molecules. By covering metal surface of SiO2@Ag with thin silica shell (~4 nm), the resulting SiO2@Ag@SiO2 was successfully applied to simultaneous detection of aniline and 4-aminothiophenol (4-ATP) without signal suppression. The SERS detection was also conducted in river water and tap water samples.
