The project\u2019s goal is to develop innovative technologies to produce <sup>67<\/sup>Cu through the direct activation route by using particle accelerators.<\/p>\n\n<p class=\"wp-block-paragraph\">Production of the radionuclide relies on high-purity solid targets irradiated with a proton beam. Following irradiation, the material undergoes a nuclear reaction that leads to the formation of the radioactive isotope of interest. In this case, the starting material is zinc highly enriched (over 98%) in its isotope with atomic mass 70 (<sup>70<\/sup>Zn), which in turn is converted, through a chemical process, into zinc oxide (<sup>70<\/sup>ZnO).<\/p>\n\n<h2 class=\"wp-block-heading\">The SPES project<\/h2>\n\n<p class=\"wp-block-paragraph\">A fundamental contribution came from the group of the <strong>SPES projec<\/strong>t at the Legnaro National Laboratories, which works on developing innovative radioisotopes for medicine. After years of research and development, it designed and produced the <sup>70<\/sup>ZnO targets, using a proprietary technology based on the process known as <strong>Spark Plasma Sintering (SPS<\/strong>). The SPS system was developed in-house, in collaboration with the group that worked on the <strong>TT-SINTER experiment<\/strong> of INFN Pavia Division.<\/p>\n\n<p class=\"wp-block-paragraph\">The targets were subsequently transferred to the Radiopharmacy Unit of the IRCCS Sacro Cuore Don Calabria Hospital, where they were irradiated with an 18 MeV proton beam produced by the institute&#8217;s cyclotron. At the end of irradiation, the resulting <sup>67<\/sup>Cu was chemically separated and purified through specific radiochemical procedures developed at the University of Ferrara.<\/p>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"629\" src=\"https:\/\/web.infn.it\/TechTransfer\/wp-content\/uploads\/2026\/09\/spettro-edited-1024x629.png\" alt=\"spectrum obtained after the complete radiochemical separation-purification procedure.

It has a half-life (T<sub>1\/2<\/sub>) of 61.8 hours, and its main feature is that it decays by emitting both \u03b2<sup>&#8211;<\/sup> particles and \u03b3 rays of suitable energy. These unique characteristics make it suitable for both therapy and medical imaging. The emission of \u03b2<sup>&#8211;<\/sup> particles, in fact, has an energy that allows its use in the treatment of various oncological conditions, while the concurrent emission of \u03b3 photons enables the acquisition of SPECT (Single Photon Emission Computed Tomography) images, a 3D imaging diagnostic system that makes it possible to assess the drug&#8217;s biodistribution, monitor therapy and perform dosimetry. Its use is particularly promising in the field of personalized nuclear medicine, especially for the treatment of tumors such as prostate cancer and glioblastoma.<\/p>\n\n<h2 class=\"wp-block-heading\">INFN&#8217;s technological role<\/h2>\n\n<p class=\"wp-block-paragraph\">INFN has for years been engaged in research in physics applied to the life sciences, with projects ranging from the development of accelerators for medical applications, to dosimetry, to the production of radionuclides for tumor diagnosis and treatment. In this context, the <strong>Legnaro National Laboratories<\/strong> are completing the construction of the <strong>SPES radioisotope production facility<\/strong>, based on a cyclotron capable of accelerating proton beams up to a maximum energy of 70 MeV, and will also be dedicated to the production of radioisotopes of medical interest. <\/p>\n\n<p class=\"wp-block-paragraph\">The <strong>SPES<\/strong> facility will enable the production of radioisotopes through two complementary technologies: <strong>on-line isotope separation<\/strong> and <strong>direct activation on solid<strong> targets<\/strong><\/strong>, significantly expanding the possibilities for research and production of innovative radionuclides. A distinctive element of these activities is the expertise developed in-house by INFN in the field of <a href=\"https:\/\/web.infn.it\/TechTransfer\/en\/portfolio_page\/sinter\/\" data-type=\"portfolio_page\" data-id=\"673\" target=\"_blank\" rel=\"noreferrer noopener\">Spark Plasma Sintering (SPS)<\/a>, a technology that makes it possible to produce advanced multi-material targets which may be used for production of radionuclides based upon the direct activation process. That is further complemented by the portfolio of <a href=\"https:\/\/web.infn.it\/TechTransfer\/en\/portfolio_page\/method-and-target-for-the-production-of-cu-67\/\" data-type=\"portfolio_page\" data-id=\"3163\" target=\"_blank\" rel=\"noreferrer noopener\">proprietary patents<\/a> covering the production process of various radioisotopes, including copper-67.<\/p>\n\n<p class=\"wp-block-paragraph\">Once operational, the SPES facility will make it possible to produce radionuclides directly at the <strong>Legnaro National Laboratories<\/strong> and, thanks to the high energies available, to develop more efficient and selective production processes. In the case of <sup>67<\/sup>Cu this will make it possible to increase the yield and improve its radionuclidic purity.<\/p>\n\n<p class=\"wp-block-paragraph\">These ongoing activities represent an important strategic investment for the future of nuclear medicine in Italy and lay the groundwork for making innovative radionuclides available for preclinical studies and future clinical applications. At the same time, they confirm the role of the INFN and <a href=\"https:\/\/www.lnl.infn.it\" target=\"_blank\" rel=\"noreferrer noopener\">Legnaro National Laboratories<\/a> as leading players in the development of advanced technologies and infrastructure serving biomedical research and health.<\/p>\n\n<h2 class=\"wp-block-heading\">Learn more<\/h2>\n\n<p class=\"wp-block-paragraph\">To have more
