Graphene detects. Ultra-sensitive sensors made from graphene could detect minute dangerous particles helping to protect potentially dangerous environments.

Graphene sensors

Graphene is an ideal material for sensors. Every atom in graphene is exposed to its environment allowing it to sense changes in its surroundings. For chemical sensors, the goal is to be able to detect just one molecule of a potentially dangerous substance. Graphene now allows for the creation of micrometre-size sensors capable of detecting individual events on a molecular level.

Reducing food waste

Graphene oxide can be used to create 'smart' food packaging products. This could dramatically cut down on unnecessary food wastage and simultaneously help prevent illnesses. Packaging which has been coated with graphene has the ability to detect atmospheric changes caused by decaying food.

Crop protection

Graphene sensors could boost the effectiveness of monitoring vital crops in the agriculture industry. Farmers would be able to monitor the existence of any harmful gasses which could impact upon crop fields and take relevant action. As graphene sensors are so sensitive it is feasible that they could determine the ideal areas for growing certain crops depending on atmospheric conditions.
