Chinese scientists extract cancer-fighting particles from rare earth minerals

Chinese researchers from the University of South China have successfully extracted cancer-fighting nuclides from rare earth minerals, Anadolu Agency reported yesterday. The team announced on Wednesday the isolation of high-purity lead-212 and bismuth-212 nuclides, which are promising for targeted alpha-nuclide therapy (TAT), a new treatment approach for cancers such as breast, pancreatic, and prostate cancer.

The research team developed a cost-effective method for separating these nuclides using a halide medium and a novel adsorbent material known as a “silica-supported anion exchange resin.” This innovative method reportedly achieves adsorption speeds more than six times faster than traditional resins, enhancing the isolation of short-lived nuclides.

Currently, the team is exploring the extraction of additional nuclides, including radium-228, thorium-228, and radium-224, which may further contribute to advancements in cancer treatment.
