The term "nanotechnology" has emerged over the past two decades as more significant than other technologies for precise target delivery in medicine, agriculture, and other fields. In the meantime, scientists are creating various kinds of nanoparticles, including coated, metal, polymer, non-polymer, and chemically mediated ones. This particular silver nanoparticle is the most well-established in various fields. Because of its size, Ag NPS development and use hold the most promise. Target drug delivery in medicine and agriculture has been made more difficult by the emergence of numerous microbial infectious diseases. However, some requirements still need to be met by the available sources. In various countries, Ag NPs are used as a product in more than 23.99% of cosmetics, 33.99% of textiles, 15.89% of construction, 50.10% of medicine, 41.76% of environmental remediation, and 36.67% of agriculture.Additionally, Ag NP had a higher capacity for sustainability and recycling than other particles. Furthermore, compared to other NPs, biologically synthesized Ag NPs improve sperm motility in rats. This chapter focuses on "Silver Nanoparticles: Technological Advances, Research Trends, and Application" in depth.
