Molecular imprinting in chemical sensing

Molecular imprinting is a universal tool for the generation of artificial a nd robust recognition systems in the gas and liquid phases. Optical and mas s-sensitive devices are suitable for trace analyses down to the ppb range. Imprinted polymers can be combined with pre-organized supramolecular hollow s, which lead to further improvements in selectivity and sensitivity. (C) 1 999 Elsevier Science B.V. All rights reserved.
