• In this work, a systematic study of surface-enhanced Raman scattering (SERS) on TiO 2 /Ag hybrid structure is presented. TiO 2 nanofibers are synthesized by the electrospinning method and are decorated with silver nanoparticles following a simple chemical route to develop TiO 2 /Ag hybrid structure. First, SERS of rhodamine 6G is measured using the TiO 2 /Ag hybrid structure and optimized the growth conditions. The fabricated SERS substrate could detect rhodamine 6G molecules with a detection limit of 10 −14  M. The enhancement factor of the order of 10 9 is observed owing to the synergetic effect of electromagnetic enhancement and chemical enhancement. The substrate is found to be reusable owing to the photocatalytic activity of TiO 2 . The multi-analyte detection capability of SERS substrate is also studied. Also, the feasibility of using the fabricated substrates for the trace level detection of insecticide imidacloprid is demonstrated.
