In recent years, functional nanoprobes with multiple imaging modalities have become an
emerging field of biomedical research. In this preliminary study, we utilized a facile hydrothermal
method for the preparation of magneto-fluorescent bimodal carbon dots doped with dysprosium
(Dy-CDs). The prepared Dy-CDs have shown a good colloidal stability in a water solution and strong
blue–green fluorescence, with a maximum at 452 nm. In addition, the excellent transverse relaxivity of
the prepared Dy-CDs (r2 = 7.42 ± 0.07 mM−1
s
−1
) makes them also suitable for T2-weighted magnetic
resonance imaging (MRI). Thus, synthesized Dy-CDs could be potentially utilized for both MRI and
fluorescence imaging of living cells.
