Abstract
A novel Surface-enhanced Raman Scattering (SERS) sensor combining with fused taper optical fiber and the film of the silver sols is proposed. We demonstrate the sensing principle and the feasibility of the SERS sensor. Accordingly, the Raman spectrum of R6G is obtained. The detecting concentration is up to 10−7M.
