radiolabeled
Tracer atom attached
Radiolabeled describes a substance that has been tagged with a radioactive isotope, allowing scientists to track its movement or behavior.
The technique is essential in medical imaging, drug development, and biological research: radiolabeled glucose reveals which tissues are metabolizing fastest.
Also spelled radiolabelled.
