© 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Halloysite nanotubes (HNTs) with surface-immobilized silver (Ag) nanoparticles (NPs) are explored as nano-templates for the surface-enhanced Raman scattering (SERS). The structure and plasmonic properties of HNTs/Ag nanocomposite during storage in water are checked by means of the transmission electron microscopy and optical absorption spectroscopy, respectively. A remarkable SERS response is observed for and the SERS activity of HNTs/Ag stored in water for 1 week decreases by several times. The observed SERS-activity is explained by desired morphology of Ag NP distribution on the surface of HNTs, which is modified during storage in aqueous medium. The revealed SERS activity of HNTs/Ag nanocomposites seems to be promising for their application in biosensorics.
