摘要
随着环境问题的日益严重,环境污染成为威胁人类健康和生态环境的世界性重大问题.表面增强拉曼光谱(SERS)以其独特的"光谱指纹"、快速响应和无损分析等优点,成为检测环境污染物的一种有效工具.SERS基底的纳米结构和便携式拉曼光谱仪的发展将促进这一新兴检测技术在未来的快速现场检测中发挥重要作用.本文介绍了 SERS应用于多环芳烃、农药、抗生素、重金属和大气颗粒物五个方面的检测技术研究进展,并提出了该技术在环境领域的可能发展方向,以期为相关领域的研究提供参考.
Abstract
With the increasing severity of environmental problems,environmental pollution have become a major global issue that poses a threat to human health and the ecological environment.Surface enhanced Raman scattering(SERS),with its distinctive"spectral fingerprinting"capability,swift responsiveness,and non-invasive analytical approach,has risen as a formidable instrument for the detection of such environmental contaminants.The advancement of SERS-based nanostructures,coupled with the advent of portable Raman spectrometers,heralds a new era for this cutting-edge detection technology,particularly in the realm of on-site rapid analysis.This review meticulously charts the research trajectory of SERS applications in the detection of polycyclic aromatic hydrocarbons(PAHs),pesticides,antibiotics,heavy metals,and atmospheric particulate.We have delineated prospective avenues for the technology's evolution within environmental sciences,with the aspiration of furnishing invaluable perspectives that will catalyze future explorations in the domain.
