 Plant nanotechnology is a relatively new field of study that focuses on understanding how nanoparticles interact with plants. Nanoparticles can be used to deliver biomolecules or stimulate plant growth and development. However, there is limited knowledge about how these particles move through the plant and what effect they have on the plant's physiology. Researchers are currently investigating the use of polymeric soft nanoparticles as a way to safely deliver biomolecules and stimulate plant growth.
