Chemical modification

Chemical modification refers to a number of various processes involving the alteration of the chemical constitution or structure of molecules.

Chemically modified electrodes[edit]

Chemically modified electrodes are electrodes that have their surfaces chemically converted to change the electrode's properties, such as its physical, chemical, electrochemical, optical, electrical, and transport characteristics. These electrodes are used for advanced purposes in research and investigation.[13]

identify which parts of a molecule are exposed to a solvent.

determine which residues are important for a particular phenotype, e.g., which residues are important for an enzymatic activity;

introduce new groups into a macromolecule; and

crosslink macromolecules intra- and intermolecularly.
