Metal-based nanoparticles (MNPs) are increasingly prevalent in the environment due to both natural processes and human activities, leading to direct interactions with plants through soil, water, and air exposure that can have beneficial and detrimental effects on plant growth and health. Understanding the uptake, translocation, and transformation of MNPs in plants is crucial for assessing environmental risks and leveraging nanotechnology in agriculture. However, accurate analysis of MNPs in plant tissues poses significant challenges due to complex plant matrices and the dynamic nature of nanoparticles. This short review summarizes recent advances in analytical methods for determining MNP-plant interactions, focusing on pre-processing and quantitative nanoparticle analysis. It highlights the importance of selecting appropriate extraction and analytical techniques to preserve nanoparticle integrity and accurate quantification. Additionally, recent advances in mass spectrometry, microscopy, and other spectroscopic techniques that improve the characterization of MNPs within plant systems are discussed. Future perspectives highlight the need to develop real-time in situ monitoring techniques and sensitive tools for characterizing nanoparticle biotransformation.
由于自然过程和人类活动，金属基纳米颗粒（MNPs）在环境中越来越普遍，导致其通过土壤、水和空气暴露与植物直接相互作用，这可能对植物生长和健康产生有益和有害影响。了解MNPs在植物中的吸收、转运和转化对于评估环境风险以及在农业中利用纳米技术至关重要。然而，由于植物基质复杂以及纳米颗粒的动态性质，准确分析植物组织中的MNPs面临重大挑战。本简短综述总结了用于确定MNP-植物相互作用的分析方法的最新进展，重点关注预处理和纳米颗粒定量分析。它强调了选择合适的提取和分析技术以保持纳米颗粒完整性和准确量化的重要性。此外，还讨论了质谱、显微镜和其他光谱技术的最新进展，这些进展改善了对植物系统内MNPs的表征。未来展望强调了开发实时原位监测技术和用于表征纳米颗粒生物转化的灵敏工具的必要性。
