“…Raman spectra of C-dots usually present two main first-order bands [3,27,32,41,88,129,[144][145][146][147][148][149]. The D band represents the vibrations of carbon atoms with dangling bonds in the termination plane of disordered graphite or glassy carbon.…”

“…In addition, NMR has been proved to be powerful in the establishment of the 8 Journal of Nanomaterials chemical alterations that happened to the surface modifiers during carbonization. For instance, Khanam et al [88] applied 1 H NMR characterization to follow the conversion of methoxy group to hydroxyl group on the surface of F-C-dots during the reaction process, and Nandi et al [165] applied 1 HNMR to confirm the transformation of the glucose residues into elemental carbon and the presence of coating alkyl chains. Although the NMR technique has merits in nondestructive nature and easy sample preparation, it is very expensive, time-consuming, and less sensitive in comparison to mass spectrometric techniques.…”

“…Based on this aspect, it has recently been used to characterize C-dots. Khanam et al [88] for the first time applied MALDI-TOF MS to acquire the molecular weight of rare C-dots and F-C-dots. The determination was carried out by using three different matrix materials, namely, sinapinic acid (SA), 2,5-dihydroxy benzoic acid (DHBA), and -cyano-4 hydroxycinnamic acid (HCCA) (Figure 9).…”

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.

“…Moreover, CNPs have shown better biocompatibility, steady fluorescence, chemical inertness and less toxicity compared to conventional heavy metal based quantum dots 11 . All these positive attributes of CNPs can be harnessed for its vital applications like cell imaging and optoelectronics 10, 13–16 .…”

A facile synthesis method for highly stable carbon nanoparticle (CNP) dispersion in acetone by incomplete combustion of paraffin candle flame is presented. The synthesized CNP dispersion is the mixture of graphitic and amorphous carbon nanoparticles of the size range of 20–50 nm and manifested the mesoporosity with an average pore size of 7 nm and a BET surface area of 366 m2g−1. As an application of this material, the carbon nanoparticle dispersion was spray coated (spray-based coating) on a glass surface to fabricate superhydrophobic (water contact angle > 150° and sliding angle < 10 °) surfaces. The spray coated surfaces were found to exhibit much improved water jet resistance and thermal stability up to 400 °C compared to the surfaces fabricated from direct candle flame soot deposition (candle-based coating). This study proved that water jet resistant and thermally stable superhydrophobic surfaces can be easily fabricated by simple spray coating of CNP dispersion gathered from incomplete combustion of paraffin candle flame and this technique can be used for different applications with the potential for the large scale fabrication.
