摘要	利用激光诱导液面自组装法制备金纳米棒光纤表面增强拉曼散射（SERS）探针,探讨制备过程中激光诱导功率和诱导时间对探针灵敏度的影响。将优化条件下（70mW,7min）制备的光纤SERS探针与便携式拉曼光谱仪联用,实现福美双、甲基对硫磷两种农药残留的高灵敏度检测,检测灵敏度分别达到10-7 mol/L和5×10-7 mol/L。探针具有良好的SERS检测重复性,相对标准差小于6%。该激光诱导液面自组装法具有操作简单、成本低廉、探针制备时间短等优点,能够实现高灵敏度光纤SERS探针的重复、批量制备;优化制备的光纤SERS探针在多种农药残留检测应用中展现出良好的应用前景。
其他摘要	Au-nanorod modified fiber surface enhanced Raman scattering（SERS）probes were fabricated by laserinduced self-assembly method in a meniscus.The influences of laser radiation power and laser radiation time on the performances of fiber probes were studied in detail.Under an optimized experimental condition as 70 mW laser power and 7 min radiation time,the fiber SERS probes with high sensitivity and good repeatability have been prepared.Further,these optimized fiber SERS probes were used to detect two typical pesticide residues of thiram and methyl parathion（MP）by combining with a portable Raman spectrometer.High detection sensitivity as10-7 mol/L for thiram and 5×10-7 mol/L for MP,and good detection repeatability with the relative standard deviation less than 6% were observed.This laser-induced self-assembly method in a meniscus has the advantages of easy operation,low cost and short preparation time,which is very useful for the fast preparation of fiber SERS probes with high sensitivity.These optimized fiber SERS probes may have potential applications in rapid and high sensitivity detection of various pesticide residues.
