被撤回的出版物: The Copper Radioisotopes: A Systematic Review with Special Interest to 64Cu (Retracted article. See art no 3860745, 2018)

Copper (Cu) is an important trace element in humans; it plays a role as a cofactor for numerous enzymes and other proteins crucial for respiration, iron transport, metabolism, cell growth, and hemostasis. Natural copper comprises two stable isotopes, Cu-63 and Cu-65, and 5 principal radioisotopes for molecular imaging applications (Cu-60, Cu-61, Cu-62, and Cu-64) and in vivo targeted radiation therapy (Cu-64 and Cu-67). 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. In recent years, Cu isotopes have been linked to antibodies, proteins, peptides, and nanoparticles for preclinical and clinical research; pathological conditions that influence Cu metabolism such as Menkes syndrome, Wilson disease, inflammation, tumor growth, metastasis, angiogenesis, and drug resistance have been studied. We aim to discuss all Cu radioisotopes application focusing on Cu-64 and in particular its form (CuCl2)-Cu-64 that seems to be the most promising for its half-life, radiation emissions, and stability with chelators, allowing several applications in oncological and nononcological fields.
