Silver nanoparticles are nanoparticles of silver of between 1 nm and 100 nm in size.

Silver Nano/micro-size particles are widely applied in various fields. Among the various particles that have been developed, silver particles are among the most important because of their favorable physical, chemical, and biological characteristics. Thus, numerous studies have been conducted to evaluate their properties and utilize them in various applications, such as diagnostics, antibacterial and anticancer therapeutics, and optoelectronics. The properties of silver particles are strongly influenced by their size, morphological shape, and surface characteristics, which can be modified by diverse synthetic methods, reducing agents, and stabilizers.

Humans and the environment are becoming increasingly exposed to silver nanoparticles, raising concerns about their safety. focused on the bactericidal and cytotoxic properties of silver nanoparticles. Silver nanoparticles have been reported to be toxic to several human cell lines. In their paper, the state-of-the-art of applications in antimicrobial textile fabrics, food packaging films, and wound dressings of silver nanoparticles in addition to the bactericidal activity and cytotoxic effect in mammalian cells are presented.They summarized the uptake, translocation, and accumulation of silver nanoparticles in plants and described the phytotoxicity of silver nanoparticles towards plants at the morphological, physiological, cellular, and molecular levels. The current understanding of the phytotoxicity mechanisms of silver nanoparticles were also discussed.
