NanotechnologyNanotechnology has the potential to completely transform agricultureAgriculture by improving crop yieldCrop yield, resource efficiencyNanoparticle efficiency, and environmental sustainabilityEnvironmental sustainability. An extensive review of plant nanotechnologyPlant nanotechnology is given in this chapter, along with an emphasis on its importance, methods, uses, and related opportunities and difficulties. Firstly, the chapter highlights how plant nanotechnologyPlant nanotechnology can be used to precisely transport genetic material, agrochemicalsAgrochemicals, and nutrients to plantsPlant, thereby addressing a number of agricultural difficulties. NanomaterialsNanomaterials such asQD-environmental interactions quantum dotsQuantum dots (QDs), nanocompositesNanocomposite, and nanoparticlesNanoparticles (NPs) provide customized approaches to enhance resource management, genetic engineeringGenetic engineering, and crop protectionCrop protection. Subsequently, it explores methods crucial to the study of plant nanotechnologyPlant nanotechnology, such as approaches for synthesis, characterization, delivery, imaging, and analysis. These approaches facilitate focused applications and the understanding of nanoparticleNanoparticles (NPs)-plant interactionsPlant interactions byNanoparticle plant interaction enabling the production, distribution, and imaging of nanomaterialsNanomaterials inside plantPlant systems. Innovative approaches to sustainable agricultureSustainable agriculture are provided by newly developed plant nanotechnologyPlant nanotechnology tools and technologies, such as nanoNano biosensors, nanoNano-enabled breeding, and nanoNano-enabled disease management. With the least amount of resource input and environmental effect possible, these developmentsDevelopment should improve agricultural productivity, stress toleranceStress tolerance, and environmental resilience. Plant nanotechnologyPlant nanotechnology presents ethical, social, legal, and commercializationCommercialization challenges in addition to its potential advantages. Concerns regarding food safety, the environment, and equal access to technology are all included in the category of ethical and social implications. To ensure safety and responsible deployment, regulatory frameworks need to take into account the special qualities and possible risks that come with nanomaterialsNanomaterials. CommercializationCommercialization challenges include scalability, cost-effectiveness, intellectual property protection, and market acceptance.
