Green Synthesis of Selenium Nanoparticles (SeNPs) Via Environment-Friendly Biological Entities

Selenium (Se) is an essential trace element for human and animal health. Se nanoparticles (SeNPs) have gained extensive attention due to its unique biological properties. The green synthesis of SeNPs via environment-friendly biological entities is gaining importance to promote the application of SeNPs due to its security and efficiency compared to conventional physical and chemical methods. SeNPs exhibit attractive biological activities including antioxidant, antimicrobial, anti-inflammatory, and anticancer. Up to now, SeNPs have been tried to apply in biomedicine, nutritional supplement, biosensor, and environmental remediation. This chapter is aimed to provide an overview about the biosynthesis strategies, mainly biological effects and potential applications of SeNPs.
