Naneum's device (the award winning Nano-ID NPS500) was designed specifically for mobile workers, who need to measure nanoparticles in a range of environments (image courtesy of Naneum) Measuring nanoparticles to improve air quality NPL helps a UK company develop an award-winning device that measures airborne nanoparticles in the environment and workplace, helping to improve air quality. The Challenge The impact on human health of airborne nanoparticles is an area of growing concern. Nanoparticles are produced from both natural and man-made sources with a substantial fraction coming from combustion and traffic. Humanity's incomplete knowledge about the environmental and health effects of nanoparticles coupled with their increasing use for industrial applications requires a precautionary
