Research Shows Chemical Coatings 'Boss' Around Bacteria

Researchers at Princeton University have developed a way to place onto surfaces special coatings that chemically "communicate" with bacteria, telling them what to do.

Researchers at Princeton University have developed a way to place onto surfaces special coatings that chemically "communicate" with bacteria, telling them what to do.

A news release from the university says that the coatings — which could be useful in inhibiting or promoting bacterial growth as needed — possess this controlling power over bacteria because, in effect, they 'speak' the bug's own language.

The new technology, reported in Nature Microbiology, contains the very same sorts of biomolecules that microbes release naturally for communicating and coordinating group behavior — a process called quorum sensing.
