纳米银修饰的超疏水界面用于农药的超灵敏检测
Construction of Nano Silver Modified Super Hydrophobic Interface for Detection of Trichlorfon Pesticides
摘要
Abstract
Super hydrophobic interface modified with silver nanoparticles was fabricated for the detection of pesticide residues.By using a chemical reduction method,silver nanoparticles were deposited on the substrate surfaces with different microscopic pore structures.Two kinds of composite substrates,including regular stainless steel mesh and cellulose polyester film,were used.The pre-treatment of the substrate with fluoridated reagents was used to form a super hydrophobic interface,which made the target molecules on the surface concentrate effectively.The surface with the cellulose polyester substrate was used to detect Rhodamine 6G (R 6G) effectively with surface enhanced Raman scattering (SERS) technique.The results showed that the detection hmit was 10-16 mol/L.In addition,the surfaces based on the stainless steel mesh and cellulose polyester substrate were used to detect trichlorfon pesticide with detection limits of 1 × 10-15 mol/L and 1 × 10-16 mol/L,respectively.关键词
