“…The applicability of this method was analyzed using fruits and it was found to be successful. 212 Huang et al reported a coumarin detection method using surface-enhanced Raman spectroscopy (SERS) paired with smart multivariate analysis. First, it was characterized by producing a flower-like silver-based substrate, and then different concentrations of coumarins were detected using this substrate as a SERS substrate.…”

Sensors are widely used owing to their advantages including excellent sensing performance, user-friendliness, portability, rapid response, high sensitivity, and specificity. Sensor technologies have been expanded rapidly in recent years to offer many applications in medicine, pharmaceuticals, the environment, food safety, and national security. Various nanomaterial-based sensors have been developed for their exciting features, such as a powerful absorption band in the visible region, excellent electrical conductivity, and good mechanical properties. Natural and synthetic coumarin derivatives are attracting attention in the development of functional polymers and polymeric networks for their unique biological, optical, and photochemical properties. They are the most abundant organic molecules in medicine because of their biological and pharmacological impacts. Furthermore, coumarin derivatives can modulate signaling pathways that affect various cellular processes. This review covers the discovery of coumarins and their derivatives, the integration of nanomaterial-based sensors, and recent advances in nanomaterial-based sensing for coumarins. This review also explains how sensors work, their types, their pros and cons, and sensor studies for coumarin detection in recent years.

“…Numerous methods have been reported to detect Cou or Ulf, such as liquid chromatography-mass spectrometry, [14][15][16] gas chromatographymass spectrometry, [17,18] and electrochemical methods. [19,20] However, these conventional detections require expensive equipment, cumbersome pretreatment processes, and high detection costs, limiting the real-time monitoring of beverage safety. In contrast, fluorescent detection can not only overcome the abovementioned defects but also exhibits a preponderance of high efficiency and high sensitivity.…”

The development of rapid, sensitive, and intuitive intelligent fluorescent materials (IFMs) for monitoring beverage safety is important for human health. In this study, an emerging IFM, a dual‐emitting Eu3+‐functionalized hydrogen‐bonded organic framework (Eu@HOF, Eu@1), is fabricated through coordination post‐synthetic modification. The ligand‐to‐metal charge transfer‐induced energy transfer (LMCT‐ET) from 1 to Eu3+ provides Eu@1 with palpable red fluorescence. Eu@1 as a sensor can specifically discriminate coumarin (Cou), a common spice used in beverages but a suspected carcinogen, with high sensitivity, high efficiency, and excellent anti‐interference. Eu@1 can also quantitatively distinguish 7‐hydroxycoumarin (umbelliferone, Ulf), a metabolite of Cou, in chromatic and ratiometric modes. In realistic milk and soy milk samples, the detection limits (DL) of Eu@1 for Cou are 0.0979 and 0.0511 mg L−1, respectively, whereas that of Ulf in practical serum samples is 0.0099 mg L−1. Furthermore, based on the polyethylene‐vinyl acetate (PEVA) films, three digital anti‐counterfeiting platforms with multiple encryption information are constructed, assisted by a support vector machine. This work proposes a facile pathway for preparing Eu@HOF fluorescent sensors to determine beverage safety and opens the possibility of designing an efficient and precise multifunctional digital anti‐counterfeiting platform via machine learning.

“…Previous studies that involved electrochemical detection of coumarin focused on monitoring coumarin levels in foodstuffs, plants, and oils as it is a physiologically toxic substance at certain levels in the body. − The electroanalytical reduction of coumarin has been shown in these studies to occur between −1.4 and −1.6 V vs Ag/AgCl reference electrode, depending on the pH of the electrolyte or buffer used for the analysis. Moreover, all mono-hydroxylated coumarins, which may possibly be formed, are also known to be electrochemically active.…”

Many recent research studies have reported indirect methods for the detection and quantification of OH radicals generated during photocatalysis. The short lifespan and high reactivity of these radicals make indirect detection using probes such as coumarin a more viable quantification method. Hydroxyl radical production is commonly monitored using fluorescence spectroscopy to determine the concentration of the compound 7hydroxycoumarin, which is formed from hydroxyl radical attack on coumarin. There are, however, a number of additional hydroxylated coumarins generated during this process, which are less amenable to detection by fluorescence spectroscopy. Consequently, limitations and inaccuracies of this method have previously been reported in the literature. As an alternative approach to those previously reported, this work has developed an electrochemical screening method using coumarin as a OH radical trap, that is capable of in situ monitoring of not only 7-hydroxycoumarin, but all the main mono-hydroxylated products formed. As a result, this technique is a more representative and comprehensive method for the quantification of OH radicals produced by photocatalysts using coumarin as a probe molecule. Moreover, the electroanalytical method provides a portable, rapid, sensitive, and accurate in situ method for the monitoring of OH radical formation without the need for sample preparation.
