Chelating Agent
Chelating agents are multifunctional compounds designed to form stable complexes with metal ions through multiple coordinating atoms such as nitrogen, oxygen, or sulfur. Widely used in molecular imaging, radiopharmaceutical development, targeted radionuclide therapy, and diagnostic applications, chelating agents enable precise delivery and stabilization of metal ions including gadolinium, lutetium, copper, and gallium. Among them, DOTA and related macrocyclic chelators are highly valued for their exceptional thermodynamic stability, metal-binding affinity, and structural versatility in MRI contrast agents, nuclear medicine, and theranostic applications.

DOTA Chelators
DOTA chelators are macrocyclic multidentate chelating agents widely used for stable coordination of diagnostic and therapeutic metal ions in radiopharmaceuticals and molecular imaging applications. Due to their high thermodynamic stability and strong metal-binding capability, DOTA derivatives are extensively applied in MRI contrast agents, targeted radionuclide therapy, PET imaging, and theranostic drug development.
Targeted Radionuclide Therapy
Targeted radionuclide therapy is an advanced therapeutic strategy that utilizes metal-chelator complexes to selectively deliver radioactive isotopes to diseased tissues or tumors. Chelating agents such as DOTA play a critical role in stabilizing radiometals including lutetium-177, yttrium-90, and copper-64 for precision oncology, nuclear medicine, and targeted radiotherapy applications.
