英文摘要A novel and rapid method to detect cocaine in human urine has been developed by using self-assembly ordered two dimensional (2D) gold nanoparticles (GNPs) film as surface-enhanced Raman spectroscopy (SERS) substrates. In order to obtain high sensitivity, uniformity, and reproducibility of SERS platform, quasi spherical, uniform GNPs were firstly synthesis using seed growth method, in which the GNPs have been functionalized with CTAB to form orderly close-packed GNPs film as SERS substrate. Importantly, the high-performance GNPs on solid substrates can produce a high yield of sub-10-nm gaps which can generate gigantic signals enhancement for analytes adsorbed GNPs surface. In view of the complex component of human urine, we develop a rapid and efficient pretreatment strategy for separation and purification of cocaine by using hexane extraction in real human urine samples within 3 min. With the advantages of better extraction rates (> 75%) examined by ultraperformance liquid chromatography (UPLC) and the excellent signal-to-noise ratio detected by SERS, our pretreatment procedure can efficiently lower the interference of complex biological components in urine. To reach on-spot analyzer, a handheld Raman spectrometer was used for feasible SERS detection of cocaine in real human urine. The favorable results demonstrated our pretreatment strategy combined with SERS platform will be a great prospective method toward rapid, reliable, and on-spot cocaine detection for public safety.
