Molecularly imprinted polymers, or MIPs, are artificial receptors developed thanks to the molecular imprinting technology, which allows the formation of specific binding sites created in a polymeric matrix. Since the size, shape, and functional groups of these cavities complement a target molecule (template) with high selectivity and specificity, MIPs can be employed to mimic the molecular recognition capabilities of natural biological receptors. The advantages of MIPs over natural receptors include superior mechanical strength, resistance to harsh environmental conditions (like high temperatures and pressures), lower production costs, simplicity of synthesis, and remarkable template selection versatility. A wide range of industries, including drug delivery, biosensing, separation science, purification, analytical assays, catalysis, and artificial antibodies, have become increasingly interested in MIPs due to these features.
