Using precisely engineered molecules with a definite structure to act as a chemical sieve so that only the target molecule (in this case, carbon dioxide) will be trapped. This principle of a chemical sieve had been used in filtration processes in the form of zeolites

However, this latest development comes from the pharmaceutical field utilising the automated and high-speed chemical screening process in the testing and selection of very specific properties of chemical products. Now, we just need a few more specific chemical sieves for the indoor pollutants that we get in museums.
