Abstract: Background: Molecular imprinting can be used to prepare antibody and receptor mimics. We have previously shown that acrylic acid polymers can be imprinted to recognize a variety of small molecules. Here, we show that molecularly imprinted polymers (MIPs) can selectively recognize steroid structures. Results: Artificial antibodies mimicking the binding performance of natural anti-corticosteroid antibodies have been prepared using a molecular imprinting protocol with either cortisol or corticosterone as a target molecule. The binding characteristics of a range of structurally related ligands were estimated using a form of radioimmunoassay. The antibody mimics were found to be highly selective for the ligands used in their preparation and the cross- reactivities with compounds of related structure resembled those obtained in studies with natural antibodies. Conclusions: The binding properties of MIPs, prepared against corticosteroids, exhibit strong similarities to those of naturally raised antibodies. Such artificial antibodies may serve as a useful complement to their natural counterparts in studies of corticosteroid binding events
