Copper (Cu) is an important trace element in humans; it plays a role as a cofactor for numerous enzymes and other proteins crucial 63 for respiration, iron transport, metabolism, cell growth, and hemostasis. Natural copper comprises two stable isotopes, Cu and 65 60 61 62 64 Cu, and 5 principal radioisotopes for molecular imaging applications ( Cu, Cu, Cu, and Cu) and in vivo targeted radiation 64 67 therapy ( Cu and Cu). The two potential ways to produce Cu radioisotopes concern the use of the cyclotron or the reactor. A noncopper target is used to produce noncarrier-added Cu thanks to a chemical separation from the target material using ion exchange chromatography achieving a high amount of radioactivity with the lowest possible amount of nonradioactive isotopes.
