In his classical studies on newly hatched goslings Konrad Lorenz analysed the development of social binding and established the term ‘imprinting’ to describe this process. WitrynaMolecular imprinting is an outstandingly favorable route to generate customized affinity pockets in a highly cross-linked polymer matrix for the targeted molecules.
