With their excellent biocompatibility, adjustable size, and high specific surface area, silica nanoparticles (SiO NPs) offer an alternative to traditional bulk fertilizers as a means to promote sustainable agriculture. SiO NPs have been shown to promote the growth of plants and to reduce the negative effects of biotic and abiotic stresses, but their bioaccumulation is a crucial factor that has been overlooked in studies of their biological effects. In this review, the techniques to quantify and visualize SiO NPs in plants were examined first. We then provide a summary of the current state of knowledge on the accumulation, translocation, and transformation of SiO NPs in plants and of the factors (, the physicochemical properties of SiO NPs, plant species, application mode, and environmental conditions) that influence SiO NP bioaccumulation. The challenges in analyzing NP-plant interactions are considered as well. We conclude by identifying areas for further research that will advance our understanding of NP-plant interactions and thus contribute to more sustainable, eco-friendly, nano-enabled approaches to improving crop nutrient supplies. The information presented herein is important to improve the delivery efficiency of SiO NPs for precision and sustainable agriculture and to assess the safety of SiO NPs during their application in agriculture.
具有极好的生物相容性、可调节的尺寸和高的比表面积，硅纳米颗粒（SiO NPs）作为一种促进可持续农业的手段，为传统的大量肥料提供了一种替代方案。SiO NPs 已被证明能促进植物的生长，并减少生物和非生物胁迫的负面影响，但它们的生物累积是其生物学效应研究中被忽视的一个关键因素。在这篇综述中，首先检查了用于定量和可视化植物中 SiO NPs 的技术。然后，我们总结了当前关于 SiO NPs 在植物中的积累、转运和转化以及影响 SiO NP 生物累积的因素（SiO NPs 的物理化学性质、植物种类、应用模式和环境条件）的知识现状。还考虑了分析 NP-植物相互作用的挑战。最后，我们确定了进一步研究的领域，这将有助于我们更好地理解 NP-植物相互作用，从而为提高作物养分供应的精准和可持续的、环保的纳米技术方法做出贡献。本文所提供的信息对于提高 SiO NPs 的传递效率以实现精准和可持续农业，以及评估 SiO NPs 在农业应用中的安全性非常重要。
