Whether it's off-gassing from the paint on the walls, the carpet on the floor or the furniture in the room, there are numerous sources of indoor air pollution that can ultimately lead to so-called "sick building syndrome." There are already devices that can detect such pollutants, although their sensitivity is generally limited to concentrations of parts-per-million. Now, however, scientists have created a sensor that can detect airborne CO2 molecules and volatile organic compound (VOC) gas molecules down to parts-per-billion.
