For example, well characterized PVP-coated AgNPs were used in A549 cells (human lung cancer cells) to study reactive oxygen species production leading to programmed cell death. On the other hand, silver nanoparticles have a potential in the treatment of cancer or degenerative Alzheimer’s disease because of their antioxidant properties. In view of the mentioned fact, the AgNPs are studied as antibacterial agents to inhibit resistant strains by multiple mechanisms of action, involving induction of oxidative stress, inhibition of DNA replication, or interaction with enzymes and proteins. Īntimicrobial properties are typical for silver and its compounds including silver nanoparticles (AgNPs). Unique chemical, physical, and biological properties lead to broad range of applications in electronics, sensors, spectral analysis, catalysis, or pharmaceutical industry in finding new ways of drug synthesis. Nanoparticles, in general, are particles of size 1–100 nm and are considered extremely small as the term “nano” means dwarf (from Greek νάννος) in the meaning of extremely small. Nanoscience and nanotechnology have been introduced as interdisciplinary fields in biology, chemistry, physics, and bioengineering.
