Revolutionary new weapon in air pollution fight -- ScienceDaily

Project leader Professor Kourosh Kalantar-zadeh, from RMIT's Centre for Advanced Electronics and Sensors, said the negative impact of nitrogen dioxide could be prevented by access to personalised, highly selective, sensitive and reliable monitoring systems that could detect harmful levels of the gas early. "The revolutionary method we've developed is a great start to creating a handheld, low-cost and personalised NO2 sensor that can even be incorporated into smartphones," Kalantar-zadeh said.
