    • This invention relates to the development of a new Raman enhancing reagent and a surface-enhanced Raman scattering (SERS) method for rapid and ultra-sensitive detection and identification of perchlorate (ClO4−) and other anions such as technetium (TcO4−), uranium and nitrate in environmental samples. The method involves the synthesis of controlled gold nanoparticles which are modified with amine functional groups such as 2-(dimethylamino)ethanethiol and N,N,N-trimethylaminethiol. These functionalized Au nanoparticles were found to be reactive with perchlorate and other anions and can be used to detect these anions by Raman spectroscopy at ultra low concentrations in complex environmental matrices. This invention overcomes the limitations of currently-available analytical techniques by offering an inexpensive, rapid, ultra-sensitive, and real-time identification and detection of perchlorate and other anions. The technique is not only sensitive but also highly specific because of the unique Raman vibrational bands of perchlorate and other anions.
    • 本发明涉及新型拉曼增强试剂和表面增强拉曼散射(SERS)方法的开发,用于快速和超灵敏检测和鉴定高氯酸盐(ClO4-)和其他阴离子如锝(TcO4-),铀 和硝酸盐在环境样品中。 该方法涉及用胺官能团如2-(二甲基氨基)乙硫醇和N,N,N-三甲基氨基硫醇修饰的受控金纳米颗粒的合成。 发现这些官能化的Au纳米颗粒与高氯酸盐和其它阴离子反应,可用于通过拉曼光谱法在复杂环境基质中以超低浓度检测这些阴离子。 本发明通过提供廉价,快速,超灵敏和实时鉴定和检测高氯酸盐和其他阴离子来克服当前可用的分析技术的局限性。 由于高氯酸盐和其他阴离子的独特的拉曼振动带,该技术不仅敏感,而且具有高度的特异性。
