Low-cost and large-scale flexible SERS-cotton fabricas a wipe substrate for surface trace analysis

摘要：

　　Thelarge-scale surface enhanced Raman scattering (SERS) cotton fabrics were fabricated based on traditionalwoven ones using a dyeing-like method of vat dyes, where silver nanoparticles (Ag NPs) were in-situ synthesized by dipping-reducing-drying process.By controlling the concentration of AgNO3 solution, the optimal SERS cotton fabric was obtained, which had a homogeneous close packing of Ag NPs.The SERS cotton fabric was employed to detect p-Aminothiophenol (PATP).It was found that the new fabric possessed excellent reproducibility (about 20%), long-term stability (about 57 days) and high SERS sensitivity with a detected concentration as low as 10-12 M.Furthermore, owing to the excellent mechanical flexibility and good absorption ability, the SERS cotton fabric was employed to detect carbaryl on the surface of an apple by simply swabbing, which showed great potential in fast trace analysis.More importantly, this study may realize large-scale production with low cost by a traditional cotton fabric.
