基于凹形金纳米箭头的苹果汁中福美胂的SERS检测
Detection of Asomate in Apple Juice Based on Surface Enhanced Raman Scattering Combined with AuCNAs
摘要
Abstract
Surface enhanced Raman spectroscopy(SERS)is an analysis technique that improves Ra-man signals through rough metal nanoparticles,with the advantages of high sensitivity,strong speci-ficity and simple operation.Therefore,this paper proposed a method to rapidly detect the residue of asomate in apple juice using concave Au nano-arrows(AuCNAs)as SERS substrate.The Au nanorods(AuNRs)were prepared based on seed-mediated growth strategy,and then used for the synthesis of AuCNAs.After that,the synthesized AuCNAs were analyzed to show good stability,homogeneity and repeatability.Meanwhile,the AuCNAs achieved high enhancement factor(1.10×106).Com-pared to other nanospheres and nanorods,AuCNAs had significantly better SERS enhancement prop-erties.The locations of SERS peaks can be attributed to the vibrations of chemical bonds through mo-lecular simulation.The intensity at the Raman peak of 1 382 cm-1 was used to establish a correction curve with the residual concentrations of asomate in apple juices,and the limit of detection(LOD)of asomate was 8.93 nmol/L.The recovery experiments showed that the average recoveries of asomate in apple juice was 96.2%-109%with relative standard deviations ranging of 4.2%-8.8%.The results in-dicated that AuCNAs can be used as SERS enhanced substrates to detect asomate in apple juice.关键词
