Molecular imprints as artificial antibodies — a new generation of chemical sensors

Abstract Highly cross-linked polymers containing molecular hollows generated by the method of molecular imprinting are chemically and mechanically stable sensitive materials that are highly suitable for being used in rough environments. We prepared layers also for detection of PAHs in drinking water as to follow engine oil degradation. Different polycyclic aromatic hydrocarbons can be monitored in drinking water down to concentrations of several ng/l by fluorimetric or mass sensitive methods. Even analysis of lubricant degradation processes is possible despite their high complexity: layers imprinted with fresh oil and its used counterpart show selective incorporation of the lubricant they were synthesized with.
