Molecular imprinting can be used to generate selective cavities—which are required for sensors—more easily than traditional synthesis. Polyurethanes with exactly adapted cavities, created by the evaporation of solvent vapors, are used to demonstrate the principle and also how the embedding of a dye enables optical detection to be employed. The Figure shows a polyurethane host with ethanol guest molecules.
