Conclusion and future prospective of silver nanoparticles

Nanotechnology has delivered on its claims to bring the biggest technological and scientific discoveries in a variety of fields. The potent antimicrobial activity of metallic nanoparticles broadly, and silver nanoparticles (AgNPs) in particular, is determined by a variety of morphological and physicochemical properties of the NPs. Most of the interactions of AgNPs within the human body remain unknown; as a result, the best-desired properties of AgNPs aren’t yet clearly identified. AgNPs are currently one of the most researched nanostructured materials in the classes of novel and upgraded biomaterials and biotechnologies, having outstanding applications within the pharmaceutical and cosmetic industries, wound dressing, antimicrobial treatment, textile, and food industries. Such broad and diversified use is based on the stable and easily modified features of AgNPs, such as outstanding physicochemical characteristics and excellent anticancer, antimicrobial activity, and antiinflammatory reactions. In this chapter, we intend to highlight the broad-spectrum multipurpose actions of AgNPs and emphasize on their various medicinal applications as nanomedicine. Furthermore, we explored the various ways to synthesize the AgNPs, their physicochemical properties, biological impacts and toxicity, and environmental risk, as well as their future prospects.
