Scientists agree that air pollution shortens the lives of many Europeans every year, but have had a hard time accurately measuring it. Now, thanks to new sensor technology developed at Sweden’s Chalmers University of Technology, pinpointing air pollution and calculating its effects may become much easier. This new optical nano-sensor detects nitrogen dioxide concentrations down to the parts-per-billion level. The underlying concept is an optimal phenomenon called a plasmon, which has to do with...
