biofilms

Unwanted microorganisms are a fact of life. Bugs grow everywhere we don't want them, from our showers and sinks to our toilets and toothbrushes. The scummy layers they form, called biofilms, are ugly and disgusting but mostly harmless in these settings. However, when they form on medical devices, such as catheters and implants, they can be life-threatening. A clever new material may prevent that.
