Coupling Methods . Coupling methods:. Coupling reactions involves conjugation of drugs or other . biocomponents. with polymers. In coupling reactions, the reactive functional groups on the different cross-linking and the functional groups present on the target biomolecule are to be modified. Coupling agents mediate the conjugation of the two molecules by forming a bond with no additional spacer atom..
