It its widest definition, affinity chromatography encompasses techniques from immobilized metal chelate affinity to molecular imprinting and technologies from affinity capillary electrophoresis to affinity precipitation, affinity partitioning, and affinity membranes. (1) A self-same narrow definition would focus forward specific or selective, reversible interactions between the immobilized ligand and target, conditioned on a unique topological relationship involving orientation and molecular reactions. These include biological as well as biological mimic ligands. This is an area that has seen
