摘　　要：近年来,纳米技术和纳米材料的大规模应用导致大量的金属纳米颗粒(MNPs)释放并积累到环境中。由于独特的物理化学特性及生物毒性,环境中的MNPs严重威胁到生态环境及人类健康。因此,对复杂基质样品(土壤、沉积物、水体、生物)中的MNPs进行表征具有重要意义。在已报道的各种表征MNPs的技术中,单颗粒电感耦合等离子体质谱(SP-ICP-MS)在分离、鉴定和定量复杂基质样品中的MNPs方面发挥了重要作用。该文主要介绍了SP-ICP-MS分析技术的原理及其复杂基质的样品前处理方法,评述了近年来SP-ICP-MS在环境科学、生命科学、医学MNPs分析应用中的新进展,并提出了SP-ICP-MS技术未来研究和应用的方向。In recent years,the large application of nanotechnology and nanomaterials has led to the release and accumulation of mass metal nanoparticles(MNPs)into the environment.Due to the unique physical and chemical characteristics and biological toxicity of MNPs,MNPs in the environ⁃ment pose a serious threaten to the ecological environment and human health.Therefore,it is of great significance to characterize metal nanoparticles in complex matrix samples(soil,sediment,wa⁃ter,organisms).Among the reported techniques for the characterization of MNPs,single particle in⁃ductively coupled plasma mass spectrometry(SP-ICP-MS)plays an important role in the separation,identification and quantification of MNPs in complex matrix samples.This review mainly introduces the principle of SP-ICP-MS analysis technology and the pretreatment methods of complex matrix sam⁃ples,reviews the new progress of its application in MNPs analysis in environment science,life sci⁃ence and medicine in recent years,and puts forward the direction of future research and application of SP-ICP-MS technology.
