“…The proposed radical-based mechanism involves the C 5 =C 6 bond of 1,10-phenanthroline that is initially attacked by HO • , leading to a dioxetane intermediate responsible for the CL emission (Scheme 8) [86]. The CL of the IO 4 − /peroxide system and the factors influencing the emission have been recently reviewed elsewhere [87].…”

Emission of light by matter can occur through a variety of mechanisms. When it results from an electronically excited state of a species produced by a chemical reaction, it is called chemiluminescence (CL). The phenomenon can take place both in natural and artificial chemical systems and it has been utilized in a variety of applications. In this review, we aim to revisit some of the latest CL applications based on direct and indirect production modes. The characteristics of the chemical reactions and the underpinning CL mechanisms are thoroughly discussed in view of studies from the very recent bibliography. Different methodologies aiming at higher CL efficiencies are summarized and presented in detail, including CL type and scaffolds used in each study. The CL role in the development of efficient therapeutic platforms is also discussed in relation to the Reactive Oxygen Species (ROS) and singlet oxygen (1O2) produced, as final products. Moreover, recent research results from our team are included regarding the behavior of commonly used photosensitizers upon chemical activation under CL conditions. The CL prospects in imaging, biomimetic organic and radical chemistry, and therapeutics are critically presented in respect to the persisting challenges and limitations of the existing strategies to date.

“…The highresolution N 1s spectra of Fe0.5-N-C (Figure 2a) could be deconvoluted into porphyrin-like Fe-N coordination and/or amide (399.7 eV), as well as pyridinic-(398.3 eV), pyrrolic-(401 eV), graphitic-(402.3 eV), and oxidized-(403.5 eV) N species [29][30] . Interestingly, the percentage of N centered at 399.7 eV of Fe0.5-N-C (18.49 %) was significant higher than that of N-C (14.45 %) and gradually increased with Fe content (Figure S10, Table S2), evidently verifying the formation of As commonly used natural peroxidase substrates, 3,3',5,5'-tetramethylbenzidine (TMB) and 3aminophthalhydrazide (luminol), were selected as substrates in aqueous solution to explore the influence of the central metal of M-N-C nanozymes on the peroxidase-like activity and selectivity [31][32] . In the first set of experiments, the activity of M0.5-N-C for catalyzing the oxidation of TMB with H2O2 in HAc-NaAc buffer solution was assessed by monitoring the characteristic absorption peak at 652 nm of the oxidized TMB (TMBox).…”

<a></a><a></a><a>The epoch-making breakthrough of nanoscience has brought new perspective to empolder new generation of nanozymes with enzyme-like structure and further to propel the comprehending of the structure-property relationship. Here, we report that the regulation of metal coordination center in M-N-C nanozymes (M = Fe, Co, Mn, Ni, and Cu) greatly altered their biocatalytic activities so as to selectively drive different types of enzymatic reactions. It was revealed that the intrinsic selectivity in interaction and activation of ROS by different M-N<sub>x</sub> was the origin to promote disparate types of enzyme-like reactions. This work would open a new vista of nanozymes to selectively catalyze different types of reactions, enabled by mimicking the molecular structure of natural enzymes and a further modulation.</a>

“…It has been reported that heteroatom doping will improve the optical properties of CDs, especially quantum yield (QY) and is widely applicable in chemical and biological sensing. [ 93 ] In 2011, Lin et al reported fluorescent CDs and successfully demonstrated chemiluminescence (CL) in the presence of ONOOH formed by mixing acidified H 2 O 2 and NaNO 2 . They found a linear relationship between nitrite formation of ONOOH and the CL signal produced from the carbon dots–NaNO 2 –H 2 O 2 system.…”

Carbon dots (CDs) are carbon nanoparticles with a size of less than 10 nm, and are synthesized from various sources; they have been of great interest to scientists worldwide due to their unique optical, electrical, and chemical properties. Sources of carbon are inexpensive and can be classified as a renewable natural resources. Many researchers use CDs because of their low toxicity, better water solubility, high biocompatibility, and stable photoluminescence. The simple methods for producing CDs are hydrothermal and use inexpensive equipment, have low energy consumption, simple manipulation, and one‐step preparation. Since the discovery of CDs, researchers have used them in various applications such as sensing, bioimaging, drug delivery, and catalysis. In this review, CDs synthesized from natural resources such as samples from herbs, roots, leaves, flowers, and fruit and some applications are described. This review provides a summary of carbon dots that is expected to provide further information for development of new CDs.
