Paper-based device costing Â£1 can detect toxins in water
UK-based researchers have developed a bacteria-based paper sensor costing less than Â£1 (about â¹88) for detecting toxic compounds in water. The recyclable device weighing less than 1 gram, generates an electric signal when exposed to polluted water. The team is currently investigating how to link the sensor to a smartphone for a user-friendly way of identifying safe drinking water.
