ABSTRACT
Infectious diseases (ID) are global killers and claim millions of human lives all over the world. Identifying effective drug and treatment procedures for ID is a challenging one. Nanomaterials, especially metal nanoparticles, effectively curb the population of pathogens such as bacteria, virus, and protozoa, which are the primary source of ID. In this chapter, we discuss the antibacterial, antiviral, and antioxidant properties of metal nanoparticles. The in vitro and in vivo studies of nanoparticles and their composites are also discussed. The antibacterial property of graphene nanoparticles is also highlighted in this chapter.
