A revolutionary development in modern agriculture, the incorporation of nanotechnology into genome editing systems provides imaginative responses to longstanding challenges in crop improvementCrop improvements. The precise and broad application of genome editing toolsEditing tools like CRISPR-CasCRISPR/Cas systems is hindered by the low efficiency, tissue damage, and host range restrictions of traditional geneGene delivery techniques like AgrobacteriumAgrobacterium-mediated transformation and biolistics. A potential replacement is provided by nanotechnology, which has made it possible to create biocompatible nanocarriersNanocarriers that can precisely and minimally affect off-target components while delivering genetic material and editing components straight into plant cells. These nanocarriersNanocarriers, which include metalMetal and metalMetal-oxide nanoparticles, carbonCarbon-based molecules, and biodegradable polymers, facilitate DNA-free editingDNA-free editing, improve transformation efficiency, and minimize biosafety concerns. The design and use of nanomaterialsNanomaterials in genome editing are examined in this chapter, with a focus on how they could improve crop characteristics, including nutritionalNutritional control value, disease resistance, and stress toleranceTolerance.
