Carbon nanofibers with the same chemical properties as the activated charcoal used in respirators have a similar ability to absorb chemical pollutants. Their photonic structure means that they will change color as pollutants accumulate, a warning that the filter canister has lost effectiveness. Researchers describe how they made the microsensors and demonstrate their ability to detect volatile organic compounds.
