A novel stainless steel with intensive silver nanoparticles showing superior antibacterial property

Stainless steels (SS) are one of the most widely used, affordable materials in public areas, but suffer from a lack of antibacterial property. Unfortunately, traditional steel casting alloying strategy has limits to add Ag due to the extremely low solubility of Ag in SS. The present work demonstrate...

Description
Summary:	Stainless steels (SS) are one of the most widely used, affordable materials in public areas, but suffer from a lack of antibacterial property. Unfortunately, traditional steel casting alloying strategy has limits to add Ag due to the extremely low solubility of Ag in SS. The present work demonstrates a novel powder metallurgy technology to fabricate Ag-contained SS with a unique microstructure in which the average distance between Ag particles is similar to the size of a typical bacterium, enabling the direct contact killing mechanism. Consequently, the new Ag-contained SS possesses an excellent and stable antibacterial rate of over 99%.
