“…In order to understand the possible mechanism, the CL spectra were obtained using the spectrofluorimeter with the light source taken off. From Figure , curve B, it is seen that no CL emission was present in the luminol solution, and the maximum wavelength of the GO–luminol and the GO–luminol–PUE systems was at 425 nm, which was similar to that of the luminol–H 2 O 2 CL system . Therefore, the luminophor in GO–luminol and GO–luminol–PUE systems was also the excited state of the 3‐aminophthalate anion (3‐APA*), an oxidation product of luminol.…”

Graphene oxide (GO), one of the water-soluble derivatives of graphene, could initiate strong chemiluminescence (CL) emission of luminol in the absence of any oxidant, and then the CL intensity was inhibited by puerarin (PUE), a main component in the traditional Chinese medicine Gegen. Based on this, a novel CL method was established for the determination of PUE. This method showed a linear relationship between the CL signal and the logarithm of PUE concentration in the range 0.01-6.00 μM. The limit of detection was 2.83 nM and the relative standard deviation (RSD) was 1.94% for 11 determinations of 0.4 μM PUE. This method was successfully used for the determination of PUE in Gegen and human urine samples. The possible CL reaction mechanism was investigated by UV-vis, fluorescence, and CL spectra, as well as by some chemical experiments.

“…In other words, the addition of CTAB–CDs did not lead to the generation of a new emitter, and they only acted as the catalysts to accelerate the electron‐transfer and the breakdown of H 2 O 2 to 1 O 2 intermediate, as shown in Figure . The 1 O 2 ‐induced CL enhancement has been further confirmed by Han and coworkers . They reported that the hollow fluorescent carbon nanoparticles (HFCNs) and solid fluorescent carbon nanoparticles (SFCNs) could both enhance the CL of the luminol–H 2 O 2 system, and the enhanced capability of HFCNs was superior to SFCNs.…”

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.

“…Unlike semiconductor QDs, which uses heavy metal elements, this nanoparticle is generally small oxygenous carbon nanoparticles, which imparts easy modification, excellent water solubility, better biocompatibility, low toxicity, high chemical stability and low environmental hazard [8][9][10][11] . For these reasons, CNPs were successfully used for bioimaging 12 , DNA biosensing 13 , drug delivery 12 , photocatalysis 14 and fluorescence probing 15 .…”

Biologically derived carbon-based nanomaterials have been gaining attention in the recent years due to its various potential medical applications. In this study, fluorescent carbon nanoparticles (FCNPs) derived from an abundant alga, Cladophora vagabunda, is first reported. FCNPs with an average diameter of ~43 nm was synthesized via hydrothermal process, a simple and green method. The synthesized FCNPs exhibited absorbances in the ultraviolet to visible regions and emissions at 600 and 650 nm. Phytochemical screening and bioactivity tests were conducted to determine various bioactive compounds present in the FCNP surface and its antibacterial, antioxidant, and cytotoxic properties. Results showed that FCNPs from C. vagabunda contains tannin, saponin, flavonoids, and phenolic compounds which are known for their antimicrobial property as supported by the result of agar well diffusion method using a Gram-positive S. aureus and Gram-negative E. coli. Moreover, FCNPs shows inactive cytotoxicity using brine shrimp lethality test at ratio as high as 1:1 in 40% (v/v) ethanol. The results suggest the potential use of FCNPs from C. vagabunda as a fluorescent material with various biological activities.
