Synthesis and Characterization of Selenium Nanoparticles Using Natural Resources and Its Applications

Abstract

Selenium is the important trace element required in fewer amounts for the human body for its function. Selenium nanoparticles are synthesized by several methods using the biological method as well as both chemical and physical method. Many papers have reported the synthesis of selenium nanoparticles using biological sources such as bacteria, fungi, yeasts, and plants. Also, chemicals have used as reducing agent for the conversion of sodium selenite into selenium nanoparticles. Synthesized selenium nanoparticles are characterized using TEM, SEM, FTIR, XRD, and UV-vis. In our book chapter, we have reviewed about the green synthesis of the selenium nanoparticles such as bacteria, fungi, plants (leaves, seeds, and flower), and yeast. The application of the prepared selenium nanoparticles is also explained in this book chapter.
