Technetium nuclear medicine, role

Among the metals which have achieved prominence only recently, molybdenum must certainly occupy first place. It has attracted interest chiefly because of its role in biological processes and also because it shows a great variety of oxidation states and coordination numbers. Steifel s extensive review of molybdenum complexes covers their chemistry up to 1977.3 Because of their use in nuclear medicine, the complexes of technetium have received recent interest.4... 

The electrochemical investigation of technetium coordination compounds has attracted considerable attention 1, 2 ] in light of the application of complexes with the isotope Tc-99m in diagnostic nuclear medicine and in view of the expected important role of the redox properties in their biological activity.
