Keyboard graph navigation: press N for concepts or E for relations; use arrow keys, Home, and End to move; Enter selects; Shift plus Enter selects and centers; plus and minus zoom; zero fits; Escape clears the selection. Use the visible viewport buttons as alternatives to dragging, wheel, and pinch gestures.
Select a concept
Select any concept, construction junction, or annotated relation by pointer, touch, search, or keyboard.
Construction junctions are diamonds. They show where multiple structures must coexist on the same carrier and satisfy compatibility conditions.
Move selected concept
Single-pointer and keyboard alternatives to dragging. Each activation moves the selected concept one step.

Authored annotation
forms metal-based imaging and therapy agents
Authored explanation
Many radiopharmaceuticals use chelators to control radionuclide speciation, targeting, kinetic stability, and in vivo distribution.
How to interpret this relation type
The source is a material constituent, structural component, or underlying quantum field whose excitation realizes the target physical system or particle. The edge label and detail must distinguish composition from field excitation; neither implies a simple classical sum of parts.

supplies a radioactive signaling or therapy component
Authored explanation
A selected radionuclide is a material component of a radiopharmaceutical, joined to formulation and often a targeting vector; decay properties, dosimetry, purity, stability, and biology govern use.
