ABSTRACT
Nanotechnology has recently become a vital branch of contemporary research and a paradigm shift in the study of materials. Nanotechnology is gaining worldwide attention as a result of its many applications. There have been many physical, chemical, and biological processes employed to make nanomaterials, but a wide range of biological systems, including bacteria, fungi, actinomycetes, yeasts, viruses, and plants, are preferred for creating metal oxide nanoparticles. The biosynthesis of nanoparticles using plants is one of the most efficient techniques to create a quick, clean, safe, and environmentally friendly technology. If the metal nanoparticles such as platinum, silver, gold, palladium, and vanadium were produced extracellularly and in a precise manner based on their form and size dispersity, the utilization of plant biomass or extracts for this purpose would be more significant. Despite having a diverse array of species, research on using plants to create these noble metal nanoparticles is still in its infancy. The most recent advancements in the phytosynthesis of noble metal nanoparticles over the past few years are scrutinized in this chapter.
