“…The materials' properties were controlled by the amine, imine, carbonyl, and carboxylate groups on the surface of graphitic carbon, and the material was used for the detection of Hg(II) ion on a nanomolar scale in a real water sample and also for live cell imaging. The fungus Ganoderma lucidium in combination with (NH 4 ) 2 HPO 4 and EDA was used for synthesizing less toxic, biocompatible fluorescent N, P-codoped NCQDs, following a hydrothermal procedure in which the aqueous solution of the precursors was heated in an autoclave at 200 °C for 6 h. 212 The presence of hydrophilic functional groups including amines, carbonyls, and acids rendered them water soluble, and the emission spectra showed a red-shift from 340 to 400 nm upon changing the excitation wavelength from 280 to 330 nm. The N, P-codoped NCQDs were employed for the detection of 2,4dinitrophenol and 4-nitrophenol in real water and soil samples and also showed their potential in bioimaging.…”

The emergence of carbon quantum dots (CQDs) opens up new opportunities in different branches of science and technology primarily because of their conducive biocompatibility, tunable bandgaps, and unique optoelectronic properties, namely, photoluminescence (PL) and fluorescence. Although CQDs are given precedence in the literature, the large-scale sustainable synthesis and the purification of CQDs as well as the study of their effects on health and environment remain a challenge. Hence, more sustainable approaches are being developed to make this category of materials widely applicable, specifically in the context of replacing toxic metal-based QDs. Among the reported synthetic protocols employed to prepare CQDs while controlling their properties, the incorporation of various dopants, surface functionalities, and defects into CQDs offers great promises. Amongst the possibilities, nitrogen dopants contribute significantly due to their broader precursor scope, natural abundance in sustainable bioderived resources, and relatively straightforward and inexpensive synthetic protocols, leading to assorted combinations of nitrogen (N)-doped carbon quantum dots (NCQDs). Here, a brief survey is presented on the recent developments of strategies deployed for the preparation of bioderived NCQDs, emphasizing the uniqueness of the synthetic methodology, choice of precursors, and purification strategies. In addition, characterization, properties, and applications of the selected NCQDs are highlighted. The present status and challenges are also discussed along with the future directions.

“…Therefore, doping of CDs with multiple atoms has attracted much attention, since it could create unique electronic structures due to the synergistic effects from the various doped heteroatoms in CDs. 18 Until now, co-doping of CDs with N/S, 122–125 N/P, 126 N/B, 127,128 N/S/B 129 and N/S/P 130,131 has all been reported.…”

“…For instance, in Yan and co-workers’ study, glyoxylic acid-modified CDs (GA-CDs) were used as a FRET ratiometric fluorescent probe for the detection of Cu 2+ in aqueous solution. 388 Similarly, Chen et al also applied cyclam-functionalized CDs as a FRET nanoprobe for the detection of Cu 2+ and S. 2–389 In addition to the above examples, the detection of other important metal ions such as Ag + , Cu 2+ , Cr 6+ , and Pb 2+ has also been successfully realized with CD composite-based sensing platforms. 390–401…”
