 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. Researchers have been studying the uptake, mobilization, and biological effects of nanoparticles on plants. Polymeric soft nanoparticles show promise as a safe alternative for delivering biomolecules and stimulating plant growth. Multidisciplinary collaborations between scientists from different fields are necessary to advance our understanding of plant nanotechnology and its applications in agriculture.
