radiolabelled
Tracer atom attached
Radiolabelled describes a substance that has been tagged with a radioactive isotope, allowing researchers to track its movement or metabolism through a system.
The technique is fundamental to medical imaging and biological research: radiolabelled glucose, radiolabelled antibodies.
Also spelled radiolabeled.
