A series of new gadolinium complexes have been synthesised to test the design of dual-modal probes that can display a change in fluorescence or relaxivity response upon zinc binding. By an iterative change in parameters of the probes, the compounds give insight into the design protocols required for successful imaging of zinc ions.

Upconversion nanocrystals have a lot of advantages over other fluorescent materials.
