Green Metallic Nanoparticles: Applications as Immunomodulatory and Anti-Oxidative Agents

Abstract

The goal of any scientific advancement is to improve human health and welfare. While current therapeutic approaches are helpful, there is a need for new methods to produce effective and reliable therapies. Furthermore, society needs new standards for technologies that promote environmental sustainability. Green nanotechnology plays a significant role in this regard by creating nanoparticles and nanoproducts without endangering the ecosystem or human well-being. The nanoparticles of particular interest are gold (Au) and silver (Ag) nanoparticles, that can be synthesized in a controlled size and shape and have been shown to reduce inflammation through cytokine inhibition. Copper (Cu) and selenium (Se), zinc (Zn) and zinc oxide (ZnO) nanoparticles derived from plant extracts have also demonstrated powerful antioxidant capabilities. By using environmentally friendly techniques to create nanomaterials, researchers can generate nanoparticles with significantly enhanced immunomodulatory and antioxidant characteristics, leading to vastly improved therapeutic efficacy.
