“…Because chemiluminescence is directly related to the reactant concentrations, it has been used as an ultrasensitive method for the quantification and localization of analytes that exhibit luminescence by participating in the chemiluminescence reaction. These analytes include chemiluminescence precursors, catalysts, oxidants, cofactors, sensitizers, enhancers, and inhibitors. ,− Lucigenin is the most commonly used chemiluminescent compound for O 2 •– detection. A luminol-based chemiluminescence assay was used to detect O 2 •– . , The use of lucigenin is disadvantageous because it can only detect extracellular free radicals, primarily O 2 •– , whereas luminol can detect both intracellular and extracellular deoxygenation products, including O 2 •– , H 2 O 2 , and hydroxyl ions.…”

Superoxide ion (O2(•-)) is of great significance as a radical species implicated in diverse chemical and biological systems. However, the chemistry knowledge of O2(•-) is rather scarce. In addition, numerous studies on O2(•-) were conducted within the latter half of the 20th century. Therefore, the current advancement in technology and instrumentation will certainly provide better insights into mechanisms and products of O2(•-) reactions and thus will result in new findings. This review emphasizes the state-of-the-art research on O2(•-) so as to enable researchers to venture into future research. It comprises the main characteristics of O2(•-) followed by generation methods. The reaction types of O2(•-) are reviewed, and its potential applications including the destruction of hazardous chemicals, synthesis of organic compounds, and many other applications are highlighted. The O2(•-) environmental chemistry is also discussed. The detection methods of O2(•-) are categorized and elaborated. Special attention is given to the feasibility of using ionic liquids as media for O2(•-), addressing the latest progress of generation and applications. The effect of electrodes on the O2(•-) electrochemical generation is reviewed. Finally, some remarks and future perspectives are concluded.

“…Among the numerous CL signal systems, the TCPO–H 2 O 2 system proved to be the most sensitive combination due to its high CL quantum yield . For this system, the reaction of TCPO and H 2 O 2 generates high excitation energy that is transferred to a fluorophore (like PZs or BZs, Figure ), and the fluorophore is excited to its excitation state.…”

A molecularly imprinted polymer based chemiluminescence array sensor for one‐step determination of phenothiazines and benzodiazepines in pig urine

The residues of phenothiazines and benzodiazepines in foods of animal origin are dangerous to consumers. For inspection of their abuses, this study for the first time reported on the use of a chemiluminescence array sensor for the simultaneous determination of four phenothiazines and five benzodiazepines in pig urine. Two molecularly imprinted polymers were coated in different wells of a conventional 96‐well microtiter plate as the recognition reagents. After sample loading, the absorbed analytes were initiated directly by using an imidazole enhanced bis(2,4,6‐trichlorophenyl)oxalate–hydrogen peroxide system to emit light. The assay process consisted of only one sample‐loading step prior to data acquisition, so one test was finished within 10 min. The limits of detection for the nine drugs in the pig urine were in a range of 0.1 to 0.6 pg/mL, and the recoveries from the fortified blank urine samples were in a range of 80.3 to 95%. Furthermore, the sensor could be reused six times. Therefore, this sensor could be used as a simple, rapid, sensitive and reusable tool for routine screening for residues of phenothiazines and benzodiazepines in pig urine.

“…The PO-CL reaction can be schematized in three basic steps. In the first step of the reaction, an aryl oxalate ester like TCPO [8,17]. It has been proven that H 2 O 2 rapidly decomposes to OH· radical by the catalytic action of silver nanoparticles [40].…”
