Abstract
Metallic nanoparticles are a new class of materials with applications in medicine, pharmaceutical and agriculture. Using biological, chemical and physical approaches, nanoparticles with amazing properties are obtained. Copper is one of the most-found elements and plays an important part in the normal functioning of organisms. Coper nanoparticles have superior antibacterial properties when comparing them to present day antibiotics. Moreover, apart from their antibacterial role, antifungal, antiviral and anticancer properties have been described. Although the mechanism of actions is not completely understood, copper nanoparticles can become a viable alternative in fighting multi-resistant bacteria strains. We hereby review the already existing data on copper nanoparticle synthesis, effects and mechanisms of action as well as toxicity.
Highlights
While thinking about nanomaterials, two possible definitions come to mind
Further studies need to be conducted in order effect other nanoparticles, e.g., AgNp, copper nanparticles have demonstrated an important to assess the safe use of copper nanoparticles, considering their potential toxicity
A selection of studies on copper nanoparticles, their antimicrobial activity and toxicity, and potential uses have been reviewed in the present paper
Summary
The more general one would consider nanomaterials as materials with the size of less than. The second definition is much more specific and restrictive and mentions that nanomaterials develop characteristics that depend on their size [1]. Given their numerous and unique properties—including their role in energy conversion and storage, their catalytic properties and implications in surface treatments [2]—. There is extensive research on different materials, metals, such as silver [3], gold [4], platinum [5], zinc [6], copper and their method of synthesis, as well as antibacterial properties [7]. This paper focuses on copper and its properties
