A large-scale and flexible SERS substrate based on sliver decorated nano-cone arrays and its applications for pesticide residue detection

of 0.9986, 0.9940, 0.9974 and the LOD of thiram was determined to be 0.46, 0.49 and 0.55 ppm in ethanol, apple juice and tomato juice, respectively. These results confirm the feasibility of the two-step fabrication method for large-scale, flexible Ag@R-SERS substrates and their applicability for rapid and sensitive pesticide residue detection.
