工程纳米材料的稳定同位素标记和追踪是一种强大且极其敏感的工具，已出现用于检测和量化源自此类材料的非常小的金属贡献，即使是在复杂的环境样品中。稳定同位素示踪是一种在地质科学以及代谢和营养研究中建立良好的技术，其在ENM中的应用首先由Gulson和Wong在2006年提出。1稳定同位素标记和示踪提供了优于其他类似方法的优势，如放射性示踪剂，荧光涂层，核/壳或掺杂颗粒。2虽然放射性同位素标签为精确追踪少量材料提供了极好的机会，但其应用受到成本高、保存期有限以及制备、应用、处置和监测所需的专业设施和专门知识的阻碍。这些因素限制了放射性标签的应用，因此并不可行
Stable isotope labelling and tracing of engineered nanomaterials (ENMs) is a powerful and extremely sensitive tool that has emerged for the detection and quantification of very small contributions of metals originating from such materials, even in complex environmental samples. Stable isotope tracing is a technique that is well established in geological sciences as well as metabolic and nutritional studies, and its application to ENMs was first suggested by Gulson and Wong in 2006. 1 Stable isotope labelling and tracing offers advantages over other similar methods such as radioactive tracers, fluorescent coatings, and core/shell or doped particles. 2 Whilst radioactive isotope labels provide excellent opportunities for precisely tracing small quantities of material, their application is hindered by their high cost, limited shelf life and the specialist facilities and expertise required for preparation, application, disposal and monitoring. These factors limit the application of radioactive labels and they are therefore not a feasible option
