摘要
塑料由于其重量轻、可塑性强、成本低等诸多优点得到广泛应用,然而,在给人们的生产生活带来便利的同时,塑料降解产生的微/纳塑料(Micro/Nano-Plastics,MNPs)颗粒也对生态环境与人体健康产生威胁。为此,发展高效且可靠的MNPs检测技术迫在眉睫,拉曼光谱技术在MNPs检测方面具有良好潜力。通过对拉曼光谱技术在MNPs检测中的应用进行综述,为后续的研究提供参考。拉曼光谱(Raman Spectroscopy,RS)是一种通过检测样品中分子振动并直接观察其振动的空间分布以确定待测样品化学结构、物相、结晶度和分子相互作用等信息的技术。随着诸如SERS、TERS、SHINERS和CARS等技术的不断发展以及拉曼光谱技术与显微镜等辅助技术或算法的结合,以拉曼散射为基础的检测技术使MNPs检测的灵敏度显著提高,并在生态环境、人生活环境和生物样品MNPs检测中发挥着重要的作用。
Plastics have been widely used due to their light weight,high plasticity,low cost,etc.However,while bringing convenience to people′s production and life,micro/nano-plastics(MNPs)particles produced by plastic degradation also pose a threat to the ecological environment and human health.Therefore,the development of efficient and reliable MNPs detection technology is urgent,and Raman spectroscopy has a good potential for the detection of MNPs.The purpose of this paper is to review and summarize the application of Raman spectroscopy in the detection of MNPs,in order to provide a reference for the subsequent research.Raman Spectroscopy(RS)is a technique to determine the chemical structure,physical phase,crystallinity and molecular interactions of the sample by detecting the molecular vibrations in it and directly observing the spatial distribution of the vibrations.With the continuous development of technologies such as SERS,TERS,SHINERS and CARS,and the combination of Raman spectroscopy with auxiliary technologies such as algorithms or microscopy,Raman scattering-based detection techniques have significantly improved the sensitivity of the detection of MNPs,and have played an important role in the detection of MNPs in ecological,and human living environments,as well as biological samples.
