Recent years have witnessed remarkable development in the field of nanotechnology and it has been affirmed that carbon-based nanomaterials have wide applications in agriculture, industrial, biomedical and environmental sectors. Due to distinctive physicochemical properties of the carbon nanotubes (CNTs), they have been extensively utilized in plant science as a growth promoter, and thus, could be a boon for biomass production of agricultural products. Studies suggest that CNTs help increase the plant’s ability to absorb water and essential nutrients, thereby increasing growth. Apart from this, CNTs have been scrutinized for their utilization in genetic engineering for the delivery of genes, proteins or drugs. However, the literature discloses mixed effects of CNTs exposure on plants like in inducing oxidative stress by generating reactive oxygen species (ROS). Moreover, studies concerning CNTs interaction with plant system is at a nascent stage and needs further investigations to explore the mechanisms influencing the growth and toxicity in plants. Therefore, this review attempts to highlight the current literature on CNTs (including both single walled and multi walled) exposure on plants. It also explores unresolved challenges, as well as recommendations to ensure sustainable development of CNTs while minimizing any possible adverse health impacts.

近年来见证了纳米技术领域的显着发展，并且已经确认碳基纳米材料已在农业，工业，生物医学和环境领域得到了广泛的应用。由于碳纳米管（CNT）的独特理化特性，它们已在植物科学中作为生长促进剂得到广泛利用，因此可能成为农产品生物质生产的福音。研究表明，碳纳米管有助于提高植物吸收水分和必需养分的能力，从而促进植物生长。除此之外，对于碳纳米管在基因工程中用于传递基因，蛋白质或药物的用途也受到了严格审查。然而，文献公开了碳纳米管暴露于植物的混合效应，例如通过产生活性氧（ROS）诱导氧化胁迫。此外，有关碳纳米管与植物系统相互作用的研究尚处于萌芽阶段，需要进一步研究以探索影响植物生长和毒性的机制。因此，本综述试图突出有关植物上碳纳米管（包括单壁和多壁）暴露的最新文献。它还探讨了尚未解决的挑战，并提出了建议，以确保碳纳米管的可持续发展，同时最大程度地减少对健康的不利影响。这篇综述试图突出关于植物的碳纳米管（包括单壁和多壁）暴露的最新文献。它还探讨了尚未解决的挑战，并提出了建议，以确保碳纳米管的可持续发展，同时最大程度地减少对健康的不利影响。这篇综述试图突出关于植物的碳纳米管（包括单壁和多壁）暴露的最新文献。它还探讨了尚未解决的挑战，并提出了建议，以确保碳纳米管的可持续发展，同时最大程度地减少对健康的不利影响。
