Plant-Mediated Synthesis and Characterization of Zinc Oxide Nanoparticles

Nanotechnology, one of the fastest growing branches of science, revolutionized traditional science in every aspect. The world is witnessing the swing of every aspect of science toward nanotechnology. This science provides more surface functionality in the given volume, but sometimes other characters are too improved compared to the original or bulky materials. Zinc and zinc-based products are in high demand due to their use in almost all fields that service humanity. Zinc at its nano-range proved more potent than the normal one, and zinc oxide nanoparticles are presently used in every industry (paints, rubber, cosmetics, food, bio-imaging, pharmacognosy, and pharmacology). Further, zinc oxide nanoparticles synthesized by the green route promote their use frequently due to their nontoxic, more stable and easier to synthesize, and excellent biocompatibility compared to the other methods. This chapter attempts to summarize the importance of zinc oxide nanoparticles, their synthesis, and the different tools used to characterize the synthesized nanoparticles.
