“…Yang et al succeeded in using C-dots for the in vivo studies of optical imaging with mice for animal test. Followed by these, as a result of extensive and multidisciplinary efforts, C-dots have found their place in a wide range of applications in nanoprobes [56][57][58][59][60][61][62][63][64][65][66], drug delivery [67][68][69][70][71], therapy [72][73][74][75][76], and optoelectronic devices [77][78][79][80][81][82].…”

Carbon nanodots (C-dots) are recently discovered fluorescent carbon nanoparticles with typical sizes of <10 nm. The C-dots have been reported to have excellent photophysical and chemical characteristics. In recent years, the advances in the development and improvement in C-dots synthesis, characterization, and applications are burgeoning. In this review, we introduce the most commonly used techniques for the characterization of C-dots. The characterization techniques for C-dots are briefly classified, described, and illustrated with applied examples. In addition, the analytical separation methods for C-dots (including electrophoresis, chromatography, density gradient centrifugation, differential centrifugation, solvent extraction, and dialysis) are included and discussed according to their analytical characteristics. The review concludes with an outlook towards the future developments in the characterization and the analytical separation of C-dots. The comprehensive overview of the characterization and the analytical separation techniques will safeguard people to use each technique more wisely.

“…Based on this finding, the CL system was developed to measure nitrite in pure milk, pond water and river water with satisfactory results. [36] As an extension of this previous report, the same group found that the CL intensity of ONOOH-carbonate system was enhanced greatly by CDs, [66] which was stronger than the CL intensity obtained in the CDs-NaNO 2 -H 2 O 2 system. In this process, the reaction of ONOOCO 2 − and its related CO 3 ·radical yielded excited carbon dioxide, (CO 2 ) 2 *.…”

“…At last, a majority of CL originated from CDs*, which was generated through energy transfer between (CO 2 ) 2 * (energy donor) and CDs (energy acceptors). However, it was worth noting that a fraction of CL arouse from the radiative electron‐hole annihilation between CD ·+ and CD ·‐ because of the partially overlapping between the two CL spectra for CDs–NaNO 2 –H 2 O 2 –carbonate system and CDs–NaNO 2 –H 2 O 2 system . The CL mechanism of CDs–NaNO 2 –H 2 O 2 –Na 2 CO 3 system is schematically illustrated in Figure .…”

Carbon dots‐involved chemiluminescence: Recent advances and developments

In recent years, more and more nanomaterials‐based chemiluminescence (CL) systems have appeared to improve the sensitivity and expand the scope of the analytical applications with the explosive growth and development of nanomaterials and technology. As a fascinating class of luminescent carbon nanomaterials, carbon dots (CDs) are now substantially studied in fabricating CL based assays due to their unique optical and mechanical properties. Herein, we summarize and highlight the current developments of CDs‐involved weak or ultraweak CL systems, as well as the corresponding mechanisms and proper applications in some fields. CDs can take part in the CL reactions as oxidants, emitting species directly involved in redox oxidation, energy acceptors of CL energy transfer, or even catalysts involving other luminophores. In fact, they always have more than one role in many cases, owing to the formation of various excited species with short life in CL systems. Therefore, in this review article, the most recent progress of the different CDs‐assisted CL systems including the mechanisms and applications are presented. Finally, the conclusions and future prospects of this field are also discussed. The significant features of the CDs‐based CL systems may open up new prospects and challenges in a wider range of fields.

Carbon dots (CDs) are a recently discovered class of fluorescent nanomaterials with great potential to be applied in the analytical field. CDs have demonstrated to be a promising alternative to conventional organic fluorophores or quantum dots as optical nanoprobes for sensing different chemical species. In this overview, we review the progress in the design of novel nanoprobes based on fluorescent CDs for inorganic trace analysis. Representative examples of CD-based assays are described and the different sensing strategies are discussed.
