Previous research had shown that another bacterium found on gold, Ischiadicus metallidurans, deals with toxicity by storing the ions inside its cells. Bacteria need some metals, such as iron ...

The compounds generated from the reaction are responsible for moving the TAMs, and moreover, the released radicals and silver ions kill the bacteria present in the medium. This bactericidal action ...

This oxidizes the silver nanoparticles, releasing silver ions (Ag+) renowned for their antibacterial properties. They are so effective that they can kill 99.9% of bacteria in just a few hours.

Researchers at ICIQ in Tarragona have developed a simple technique to produce microscopic crystals that activate in the presence of light, releasing silver ions with antimicrobial activity.
