Carbon dots (CDs) are nanostructures containing mainly carbon atoms and abundant functional groups. With remarkable adjustable physicochemical properties, CDs have excellent hydrophilicity, photoluminescence (PL), biocompatibility, low toxicity. Although the numerous advantages make a research target for synthesizing advanced materials, some limitations pertinent must be corrected. Rare earth elements (RE) candidates doping CDs, obtaining hybrid materials called RE-CDs to optimize luminescence applicability, quantum yields. Hybrids allow combination of advantageous characteristics both RE, drastically improving their luminous magneto-optical imaging performance opening door practical technological applications. To date, no studies in literature provided in-depth analyses methods used prepare RE-CDs, characterization techniques used, challenges, critical analysis what could improved synthesis by proposing solutions. fill this gap, review initially presents detailed survey RE separately. Subsequently, addressed, as well obtainment, commonly characterizations, recent applications, from analyte detection functionality medical nanodevices. Finally, criticisms suggestions future work also discussed inspire new discoveries about potential derived RE-CDs.

This work reports an "all-in-one" theranostic upconversion luminescence (UCL) system having potential for both diagnostic and therapeutic applications. Despite considerable efforts in designing nanoparticles (UCNPs) multimodal imaging tumor therapy, there are few investigating dual modality SPECT/optical theranostics. Especially, research focusing on vivo biodistribution studies of intrinsically radiolabeled UCNPs after intravenous injection is utmost importance the clinical translation such formulations. Here, we utilized gamma emission from 169Er 171Er radionuclides demonstration ZnAl2O4:171/169Er3+ as a potent agent dual-modality imaging. No uptake radio nanoformulation was detected skeleton 4 h administration, which evidenced robust integrity ZnAl2O4:169/171Er3+.
