In the recent techno-scientific revolution, nanotechnology has gained popularity at a rapid pace in different sectors and disciplines, specifically environmental, sensing, bioenergy, and agricultural systems. Controlled, easy, economical, and safe synthesis of nanomaterials is desired for the development of new-age nanotechnology. In general, nanomaterial synthesis techniques, such as chemical synthesis, are not completely safe or environmentally friendly due to harmful chemicals used or to toxic by-products produced. Moreover, a few nanomaterials are present as by-product during washing process, which may accumulate in water, air, and soil system to pose serious threats to plants, animals, and microbes. In contrast, using plants for nanomaterial (especially nanoparticle) synthesis has proven to be environmentally safe and economical. The role of plants as a source of nanoparticles is also likely to expand the number of options for sustainable green renewable energy, especially in biorefineries. Despite several advantages of nanotechnology, the nano-revolution has aroused concerns in terms of the fate of nanoparticles in the environment because of the potential health impacts caused by nanotoxicity upon their release. In the present panoramic review, we discuss the possibility that a multitudinous array of nanoparticles may find applications convergent with human welfare based on the synthesis of diverse nanoparticles from plants and their extracts. The significance of plant–nanoparticle interactions has been elucidated further for nanoparticle synthesis, applications of nanoparticles, and the disadvantages of using plants for synthesizing nanoparticles. Finally, we discuss future prospects of plant–nanoparticle interactions in relation to the environment, energy, and agriculture with implications in nanotechnology.

在最近的科学技术革命中，纳米技术已在不同领域和学科中迅速普及，特别是环境，传感，生物能源和农业系统。新型纳米技术的发展需要受控，简单，经济和安全的纳米材料合成。通常，由于所使用的有害化学物质或所产生的有毒副产物，诸如化学合成之类的纳米材料合成技术并不完全安全或对环境不友好。此外，一些纳米材料在洗涤过程中作为副产物存在，它们可能在水，空气和土壤系统中积累，对植物，动物和微生物构成严重威胁。相比之下，使用植物进行纳米材料（尤其是纳米颗粒）合成已被证明对环境安全且经济。植物作为纳米颗粒来源的作用还可能扩大可持续绿色可再生能源的选择范围，特别是在生物精炼厂。尽管纳米技术具有若干优点，但是由于纳米毒性释放纳米颗粒对健康的潜在影响，因此纳米革命引起了人们对环境中纳米颗粒命运的关注。在当前的综述中，我们讨论了从植物及其提取物中合成多种纳米颗粒的可能性，大量纳米颗粒阵列可能会发现与人类福利相融合的应用的可能性。植物-纳米粒子相互作用的重要性已进一步阐明，用于纳米粒子合成，纳米粒子的应用以及使用植物合成纳米粒子的弊端。最后，
