Poster summary

In the work Cu-doped carbon nanodots (CDs) with luminescence in the long-wavelength region were fabricated from citric acid, formamide and copper (II) chloride dihydrate. A high value of relaxivity r1 = 0.92 mM-1∙s-1 was obtained for Cu-CDs, which is the highest, to the best of our knowledge, for copper nanoparticles. The developed CDs are promising for their use as two-modal nanoprobes for luminescent and magnetic resonance (MR) imaging.
