Described in the American Chemical Society journal Langmuir, researcher Aharon Gedanken tells me that while colloidal silver is already widely used as an antimicrobial agent, what's new about his team's research is the process by which silver nanoparticles are deposited onto paper to develop antimicrobial properties.
The team was able to control both the thickness of the silver coating and particle size while using ultrasonication to attach the nanoparticles to the paper; because the coatings are highly stable and anchored so strongly to the surface, they are long-lasting.
