“…We observed that the fluorescence intensity of PABA gradually decreased with increasing BPO concentration (Figure 5A) and the negative logarithm of BPO concentration was proportional to the quenching in PABA fluorescence intensity (F 0 –F i ) with a linear relationship of Y = −198.94 X + 1819.44 (R 2 = 0.9941) in the detection range of 8.26 × 10 −9 M – 8.26 × 10 −4 M (Figure 5B). The LOD is usually obtained from three times of signals to noise (S/N = 3) [8,35,36,37,38] and the estimated LOD was 1.06 × 10 −9 M, featuring a high sensitivity. With the developed method, the ultrasensitive detection for BPO can be completed within a short time.…”

The method capable of rapid and sensitive detection of benzoyl peroxide (BPO) is necessary and receiving increasing attention. In consideration of the vast signal amplification of fluorescent conjugated polymers (FCPs) for high sensitivity detection and the potential applications of boron-containing materials in the emerging sensing fields, the organoboron FCPs, poly (3-aminophenyl boronic acid) (PABA) is directly synthesized via free-radical polymerization reaction by using the commercially available 3-aminophenyl boronic acid (ABA) as the functional monomer and ammonium persulfate as the initiator. PABA is employed as a fluorescence sensor for sensing of trace BPO based on the formation of charge-transfer complexes between PABA and BPO. The fluorescence emission intensity of PABA demonstrates a negative correlation with the concentration of BPO. And a linear range of 8.26 × 10−9 M–8.26 × 10–4 M and a limit of detection of 1.06 × 10–9 M as well as a good recovery (86.25%–111.38%) of BPO in spiked real samples (wheat flour and antimicrobial agent) are obtained. The proposed sensor provides a promising prospective candidate for the rapid detection and surveillance of BPO.

“…As shown in Table S2, there have been a variety of determination methods for BPO such as gas chromatography (GC) [28], high-performance liquid chromatography (HPLC) [29][30][31], capillary electrophoresis (CE) [32], the electrochemical method [33,34], chemiluminescence [35,36], and the other optical methods [37][38][39][40][41]. To discover the presence of BPO easily and quickly, further efforts are necessary to develop real-time methods, including colorimetric determination.…”

Using the ionic salt characteristics of CsPbBr3 perovskite nanocrystals (CsPbBr3 NCs), the fluorescence wavelength of CsPbBr3−xIx NCs could be changed by the halogen exchange reaction between CsPbBr3 NCs and oleylammonium iodide (OLAM-I). Under the excitation of a 365 nm UV lamp and the increase of OLAM-I concentration, the content of iodine in CsPbBr3−xIx NCs increased, and the fluorescence emission wavelength showed a redshift from 511.6 nm to 593.4 nm, resulting in the fluorescence color change of CsPbBr3 NCs from green to orange-red. Since OLAM-I is a mild reducing agent and easily oxidized by benzoyl peroxide (BPO), a novel colorimetric sensing approach for BPO based on the fluorescence wavelength shift was established in this study. The linear relationship between the different wavelength shifts (Δλ) and the concentration of BPO (CBPO) is found to be in the range of 0 to 120 μmol L−1. The coefficient of alteration (R2) and the detection limit are 0.9933 and 0.13 μmol L−1 BPO, respectively. With this approach, the determination procedure of BPO in flour and noodle samples can be achieved in only a few minutes and exhibit high sensitivity and selectivity.

“…However, excessive BPO not only has great safety hazards in the production of flour, but does not guarantee the actual nutritional value of flour, and even endangers people's health. On the one hand, excessive BPO destroys the nutrients in the flour, such as beta-carotene and vitamins, reducing body absorption (Hu et al 2018). On the other hand, when an excessive amount of BPO enters the human body, it decomposes into a highly dangerous oxidative free radical and converts it into a harmful substance (such as benzoic acid) that is detoxified by the liver, thereby causing liver damage (Abe-Onishi et al 2004;Wu et al 2019;Ponhong et al 2015).…”

In this paper, a simple and effective strategy was designed for colorimetric sensing of benzoyl peroxide (BPO) based on the morphological transition of silver nanoprisms (AgNPRs). The decomposition of O-O bond of BPO generated strong oxidant benzoyl oxide free radical, which could be first oxidized the silver atoms at the corner areas and the {110} facet of AgNPRs. With the increase of the BPO concentration, AgNPRs were oxidized to produce nanodisks and a blue shift of the in-plane dipole plasmon resonance peak could be observed. In addition, a distinct color change of AgNPRs solution from blue to purple, fuchsia, and finally colorless appeared with 10 min, which could be easily observed by naked eyes. Under the optimal conditions, a linear relationship between the blue shift of the in-plane dipole plasmon resonance peak and BPO concentration ranged from 2 to 80 μM with the detection limit of 0.47 μM. The practical applicability of this assay was verified by successfully determining BPO in flour samples with a good recovery, which demonstrated its great potentials in food safety field. Furthermore, a simple, inexpensive, and portable test kit for the visual detection of BPO in flour samples was also designed by utilizing agarose hydrogel as a visual detection platform. Thus, the proposed sensor provided a promising prospective candidate for the rapid detection and surveillance of BPO.
