Abstract
A sensitive and practical surface-enhanced Raman scattering (SERS) substrate, consisting of one-dimensional TiO2/Ag nanowire arrays was prepared by the high-voltage electrostatic spinning method. The fabricated substrate showed high sensitivity to the SERS signals of rhodamine 6G biomolecules, with good stability and a detection limit as low as 10−12 M. The one-dimensional composite nanostructures exhibit excellent SERS properties, with enhancement factors of 107.
