- Abstract
The industry of nanotechnology has had a rapid development in the last decades. In particular, silver nanoparticles (AgNPs) have unique properties so they can be used in different industrial applications, mainly in areas such as electronics, environment, medicine, biosensors and biotechnology; as well as household and healthcare‐related products, like cosmetics, due to their antimicrobial properties. These beneficial effects are also offset by the higher chemical reactivity of these NPs due to their surface area to volume ratio, leading to the increased formation of reactive oxygen species (ROS) within cells. AgNPs, however, have a dark side: they increase the formation of reactive oxygen species (ROS). With increased human exposure to AgNPs, the risk and safety standards have attracted much attention. This review highlights the beneficial and toxicological effects of AgNPs in terms of cytotoxicity and genotoxicity. The positive side of silver nanoparticles (AgNPs) allows them to be used in various applications; however, its negative side is associated with the formation of reactive oxygen species (ROS).
