“…CDs have different preparation methods and numerous sources (including carbohydrates, amino acids, and organic acids) that promote flexible structure modification [26][27][28][29]. In addition, CDs exhibit good electronic transfer ability and can be used to catalyze redox reactions [30][31][32][33] and to establish analysis methods. Long groups [31] prepared CDs with lampblack followed by reduction with 2 of 12 NaBH 4 to form r-CDs, which was then used to catalyze the reaction of hydrogen peroxide with 3,3 ,5,5 -tetramethylbenzidine for hydrogen peroxide detection (detection range: 0.01-0.1 mM).…”

Carbon dots (CDs) can be prepared from various organic (abundant) compounds that are rich in surfaces with –OH, –COOH, and –NH2 groups. Therefore, CDs exhibit good biocompatibility and electron transfer ability, allowing flexible surface modification and accelerated electron transfer during catalysis. Herein, CDs were prepared using a hydrothermal method with fructose, saccharose, and citric acid as C sources and urea as an N dopant. The as-prepared CDs were used to catalyze AgNO3–trisodium citrate (TSC) to produce Ag nanoparticles (AgNPs). The surface-enhanced Raman scattering (SERS) intensity increased with the increasing CDs concentration with Victoria blue B (VBB) as a signal molecule. The CDs exhibited a strong catalytic activity, with the highest activity shown by fructose-based CDs. After N doping, catalytic performance improved; with the passivation of a wrapped aptamer, the electron transfer was effectively disrupted (retarded). This resulted in the inhibition of the reaction and a decrease in the SERS intensity. When bisphenol A (BPA) was added, it specifically bound to the aptamer and CDs were released, recovering catalytical activity. The SERS intensity increased with BPA over the concentration range of 0.33–66.67 nmol/L. Thus, the aptamer-adjusted nanocatalytic SERS method can be applied for BPA detection.

Here, we report ultraspeed preparation of highly emissive nitrogen‐doped carbon dots (NCDs) using threonine and guanidine hydrochloride by the microwave irradiation method. Experimental conditions such as microwave power, irradiation time, and reactant ratio were varied to achieve high‐quality NCDs. NCDs were thoroughly characterized using transmission electron microscopy, X‐ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, UV–visible spectroscopy, and fluorescence spectroscopy. NCDs presented high aqueous solubility, bright emission with a quantum yield of 30%, and excitation‐dependent emission. Investigation of optical properties unveiled their admirable characters of tolerance to photobleaching, high salinity, pH, and long shelf life. Evaluation of their metal ion detection ability unveiled their selective fluorescence quenching response to Mn (VII), and further explorations revealed the application of NCDs as a label‐free probe for Mn (VII) detection. The probe presented a good linear response (R2 = 0.992) in the concentration range of 5–35 μM with a detection limit of 0.66 μM. Mechanistic studies disclosed that the inner filter effect was responsible for fluorescence quenching. The probe presented no significant interference and was successfully applied for the quantification of Mn (VII) in spiked real‐water samples.

“…Carbon nanodots (CDs) are considered as promising nanomaterials, because of their prominent physicochemical properties and abundant assembled structure or morphology. − With the advance in synthetic technique and clarity of mechanism, CDs reveal their versatility as a luminescent candidate, because of their high photoluminescence quantum yield (PL QY), tunable emission wavelength, good biocompatibility, high photostability, etc. − Moreover, the CDs show huge potential applications in several CL reactions, such as lucigenin–H 2 O 2 , luminol–KMnO 4 , and triethylamine–K 2 S 2 O 8 , etc. − However, the low luminance of these CL limit their applications and recent efforts rely on the indraft of high-efficiency CL system like peroxalate–H 2 O 2 system to address these issues. To date, most successful approach reported in our prior work is that a proper energy level alignment between the CDs and the energy-rich intermediate produced in the peroxalate–H 2 O 2 reaction can promote the electron transfer between the CDs and the intermediate, resulting in high CL quantum yield (CL QY).…”

Chemiluminescence (CL) has intrigued extensive interest, because of its promising applications as a cold light illuminator and in bioimaging. However, relatively low brightness and high biotoxicity of traditional CL materials such as dyes obstruct their applications. Herein, with the merit of the energy level alignment between the carbon nanodots (CDs) and the energy-rich intermediate generated in the peroxalate system, we design a facile controllable nitrogen doping route to prepare CDs for high-brightness CL. The increased amount of trigonal nitrogen restructures the CDs from a graphitic carbon core to a β-C 3 N 4 core, which triggers the lifting of the highest occupied molecular orbital and further promotes the electron exchange between the CDs and intermediate agents. Meanwhile, the restructured bonding and antibonding molecular orbitals lead to the tunable CL emission wavelength. Thus, a maximal luminance of 4.35 cd m −2 has been achieved in the CL CDs with high nitrogen content, which is the highest value ever reported previously. Besides, the CL luminophore in cold illumination and CL probes for cellular reactive oxygen species imaging have been demonstrated with these CDs. These results may provide a route to high-brightness chemiluminescent nanomaterials in displaying and bioimaging.
