Silver nanoparticles-based SERS active paper substrates

Nguyen Thi Bich Ngoc

Abstract


A flexible low-cost paper-based surface enhanced Raman scattering (SERS) substrate was successfully fabricated by direct chemical reduction of silver nanoparticles (AgNPs) onto a common commercially available filter paper. The influences of the silver nitrate concentration and type of filter paper on the substrate’s SERS effect were systematically investigated. The capability of the fabricated SERS substrate for detecting food toxic chemicals as melamine were demonstrated. The limit of detection for melamine is 10-7M.


Keywords
