南华大学医用核素提取技术又有新突破

Group 1 - The core viewpoint of the article highlights the significant breakthroughs achieved by the research team at Nanhua University in the extraction and purification of medical isotopes, particularly strontium-90 and yttrium-90, from high-level waste liquid [1][3] - The team has developed a complete technical system for the separation, purification, and drug preparation of yttrium-90, addressing China's reliance on imports for this isotope [3][4] - The innovative techniques include the use of crown ether supramolecular design and new adsorption materials, which enable efficient capture of strontium-90 from nuclear waste [3][4] Group 2 - The future market demand for yttrium-90 in China is expected to be substantial, but current domestic technologies for its preparation and clinical application require further development [3] - The research team aims to tackle the large-scale production technology of lead-212 and establish a thorium-based isotope factory, positioning itself to become the largest producer of medical alpha isotopes globally [4] - The team is also focused on the research and clinical translation of new nuclear drugs, including lead-212 and bismuth-212 labeled drugs [4]
