The recent application of sophisticated instrumentation and novel experimental techniques to environmental systems has driven the study of natural nanoparticles and nanoparticle systems towards new horizons. Moving beyond the detection of engineered nanoparticles in natural systems, these technologies create new knowledge about the composition, behaviour, and functions of natural nanoparticles as individual entities and particle systems. In this perspective article, we describe the progress and frontiers in this research area using case studies drawn from a range of published and unpublished data spanning diverse environmental systems. The companion paper defines the emerging field of environmental nanobiogeochemistry and describes the fundamentals, optimization, advantages, and disadvantages of field-flow fractionation and ICP-MS-based techniques for advancing our understanding of natural nanoscale particles and particle systems. Thus, by combining the necessary background with the most recent findings and key challenges, these contributions provide key knowledge for new and established researchers entering this exciting field and lay the groundwork for future research.
先进仪器和新颖实验技术在环境系统中的最新应用，推动了对天然纳米颗粒及纳米颗粒系统的研究迈向新高度。这些技术超越了在自然系统中检测工程纳米颗粒的范畴，为天然纳米颗粒作为个体以及颗粒系统的组成、行为和功能带来了新认知。在这篇观点文章中，我们利用一系列已发表和未发表的数据中的案例研究，涵盖不同环境系统，阐述了该研究领域的进展与前沿。配套论文定义了环境纳米生物地球化学这一新兴领域，并描述了场流分级和基于电感耦合等离子体质谱的技术在推进我们对天然纳米级颗粒及颗粒系统理解方面的基本原理、优化方法、优势与劣势。因此，通过将必要的背景知识与最新研究成果及关键挑战相结合，这些文章为初涉这一令人兴奋领域的新老研究人员提供了关键知识，并为未来研究奠定了基础。
