RMIT University researchers have used nanotechnology to create a pioneering sensor that can precisely measure one of the world’s most poisonous substances—mercury.

The mercury sensor developed by RMIT’s Industrial Chemistry Group uses tiny flecks of gold that are nano-engineered to make them irresistible to mercury molecules.
