Abstract
This chapter of the book gives a summary of the role of plants in NP synthesis. Nanoparticles come in a variety of shapes and sizes, and they have a wide range of applications in biotechnology, agriculture, pharmaceuticals, and other fields. Because of their enormous surface area and nanoscale size, nanoparticles have unique physical and chemical properties. These NPs serve a vital function in plant nutrition. The effects of diverse NPs on plants, such as changes in size, morphol¬ogy, physiology, and other aspects of these nanoparticles, aid in establishing their function during plant interaction. While exploring the merits of NPs, green chem¬istry methods for producing NPs are being established. As a direct consequence, the current research focuses on the biosynthesis of NPs from plants, which are gradually being used as nanofactories.
