Scientists at the nanoscience institute at Trinity College Dublin have come up with a revolutionary new sensor system based around graphene.

The new sensor is composed of a single one-atom thick layer of the material on a silicon surface.

The substance's extraordinary conductive and strength properties mean it can detect even the slightest change in signals when touched.

As a result, researchers at the facility, funded by Science Foundation Ireland, say it could have significant commercial applications in air quality control systems and in the detection of bacteria and parasites in drinking water.

It would also be much more cost and energy efficient than other sensors currently in existence.
