Surfaces that kill bacteria on contact could soon be a reality in our homes and hospitals, thanks to researchers from the Curie Institute in Paris. The French group has developed a method for making surfaces bactericidal that it says is straightforward and versatile enough to be widely used.Vincent Semetey and colleagues have devised a simple way to attach polymers containing quaternary ammonium groups to surfaces. Surfaces modified in this way kill any bacteria that come into contact with them.
