'Air pollution is a global health problem. To be able to contribute to increased knowledge and a better environment feels great. With the help of these small, portable sensors, it can become both simpler and cheaper to measure dangerous emissions extremely accurately,' says Chalmers researcher Irem Tanyeli, who has helped develop the small sensors, which measure nitrogen dioxide with great precision. 'Nitrogen dioxide is just one of the many substances which can be detected with the help of optical nanosensors. There are great opportunities for this type of technology,' says Christoph Langhammer.
