Prussian Blue and Its Analogs as Novel Nanostructured Antibacterial Materials

Abstract

Prussian blue is an ancient artificial pigment. Its biocompatibility and the possibility of synthesizing it in nanometric size stimulated the interest of the scientific community. Many uses of Prussian blue nanoparticles have been reported in the field of nanomedicine. More recently, interest into the potential application of Prussian blue nanoparticles as antibacterial agents has spread. Literature regarding Prussian blue and its analogs as antibacterial materials is still limited, but the number of papers has grown quickly over the last 2–3 years.

Prussian Blue: A Nanozyme with Versatile Catalytic Properties

“…Some of them are based on the photothermal effects of these nanoparticles. Recently, interesting antibacterial features of PBNPs coming from this issue have been described [11]. Such nanoparticles benefit from excellent biocompatibility and biosafety since the insoluble form of PB was approved by the Food and Drug Administration (FDA) for the treatment of exposure with cesium and thallium ions.…”
