Natural resources for nanoparticle synthesis

Drastically growing research areas are mainly dependent on nanotechnology for the purpose of a better outcome and to propose new advancements in their respective field. In fact, nanotechnology has been an attraction field for all researchers due to their outstanding key prospects in all the fields. Truly, to claim that nature also can be distinguished as a superior nanotechnologist. Nanoparticles are the subclass of nanotechnology which can be found everywhere and every time. Nanoparticles are particles with nano-sized range which are highly mobile and precise. In nature, nanoparticles can be found in volcanic ash, ocean spray, natural water, soil, plant extract, and plant biomass. Naturally, existing compounds or minerals by the bioreduction process can be either highly toxic or nontoxic to the environment. This chapter generally presents the types of nanoparticles that exist naturally and their way of production.
