Carbon Dots Doped with Dysprosium: A Bimodal Nanoprobe for MRI and Fluorescence Imaging. J. Funct. Biomater. 2018, 9, 35.http://dx.doi.org/10.3390/jfb9020035http://nur.nu.edu.kz/handle/123456789/3863In 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.enAttribution-NonCommercial-ShareAlike 3.0 United Statescarbon dotsdysprosiumbimodal nanoprobesfluorescencemagnetic resonance imaging MRIArticle
