Chalmers researchers have developed a nano-sensor to detect pollution that fits a standard streetlight. The optical sensor can detect low nitrogen dioxide levels using an optical event called a plasmon, and could be adapted to detect other gases. It has already been installed in a shopping centre in Sweden, where Chalmers University of Technology is based, and is set to be rolled out on a railway tunnel construction route in the country. Chalmers University of Technology is also collaborating with Sheffield University, which runs an air quality centre called the Urban Flows Observatory.
