Abstract :
The development of new chemical sensors for the detection of formaldehyde, a ubiquitous and carcinogenic indoor air pollutant is described. These sensors are based on the use of nanoporous matrices acting as sponge to trap the targeted pollutant and doped with Fluoral-P for a selective detection of formaldehyde. A colorimetric pollution-warning kit, which displays a progressive color change visible by eyes, is provided for homes. For a quantitative and precise measurement of the air quality in public area, a low-cost digital device is available.
