The document discusses the use of nanotechnology to improve wheat growth and yield. It outlines several nanotechnology tools that can boost wheat production, including multi-walled carbon nanotubes, hydrated graphene ribbon, titanium dioxide nanoparticles, and copper oxide nanoparticles which can enhance plant growth. It also discusses how nanotechnology can help alleviate drought and salinity stresses in wheat through tools like analcite and copper zinc nanoparticles. Nanopesticides, nanofertilizers, and nano-silica are highlighted as ways to control nutrient release and protect crops. Finally, the document presents opportunities for plant genetic modification using nanopore DNA sequencing and zinc sulfide nanoparticles and calls for more research to better understand nanoparticle interactions and properties.
