“…In these methods, H 2 O 2 can be captured with a selective color detector or can participate in an oxidation reaction of redox substrates such as 3,3′,5,5′-tetramethylbenzidine (TMB), o-phenylenediamine, and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). In the latter, peroxidase enzymes such as horseradish peroxidase catalyze the reaction 7 – 9 .…”

The hydrogen peroxide (H2O2) measurement is considered highly important in industrial wastewater quality assessment, environmental protection, and disease detection. Here, a simple high-performance paper-based sensor is proposed for rapid and in situ detection of H2O2. To this end, 3,3′,5,5′-tetramethylbenzidine is embedded in the sensor to act as a color indicator, whose reaction with hydrogen peroxide is catalyzed by a silver nanozyme modified by sericin. The result of the reaction clarified by the appearance of blue color in the sensor detection zone is received by a portable scanner, while also calculating its intensity by image analysis software. This method is sensitive to hydrogen peroxide in the concentration range of 0.5‒240 mg/dL, providing a detection limit of 0.15 mg/dL. The ability of the sensor to determine glucose is also evaluated by adding a layer containing glucose oxidase enzyme to the sensor structure. A desirable response is obtained in the range of 1.0‒160 mg/dL, together with a detection limit of 0.37 mg/dL. Accordingly, the proposed sensor shows satisfactory results compared to clinical methods for monitoring the amount of glucose in biological samples such as serum and saliva.

“…H 2 O 2 can be used as a disinfectant ingredient in nasal spray 1 , beverages 2 , and household cleansers 3 . Apart from these applications, H 2 O 2 has also been widely used in textile, water treatment, and food processes 4 . However, the misuse of H 2 O 2 preparations may be toxic to human health and the environment.…”

Hydrogen peroxide (H2O2) has attracted considerable attention for use as a disinfectant ingredient for various applications over the decades. The use of H2O2 within the safety regulations can avoid its toxicity to human health and the environment. In this study, a paper-based sensor containing green-synthesized silver nanoparticles (P-AgNPs) was developed for use in a smartphone in the determination of the H2O2 concentration. In the synthesis process, an extract of spent coffee grounds was used as a bioreducing agent. The effects of reaction time and silver nitrate (AgNO3) concentration on the green synthesis of silver nanoparticles (AgNPs) were investigated. The optimum conditions for the preparation of P-AgNPs were determined to be 100 mM AgNO3 (P-AgNPs-100) and 15 h synthesis time. The P-AgNPs-100 sensor exhibited high sensitivity with a detection limit of 1.26 mM H2O2, which might be suitable for the detection of H2O2-based household and beverage sanitizers. The H2O2 detection capability of P-AgNPs-100 was comparable to that of a commercial strip sensor. Furthermore, P-AgNPs-100 had a detection efficiency of more than 95% after long-term storage for 100 days.

“… 11 − 14 The challenge lies in the combined difficulty of molecular design and materials engineering to produce a sensor system that not only enables strong binding with H 2 O 2 (for efficient vapor sampling) but also expedient, selective reaction with H 2 O 2 to transduce the readable signal. 15 Although few papers reported on chemical sensors such as colorimetric sensors 16 − 21 that can be employed for vapor detection of H 2 O 2 , the reported sensors either suffer from the long response time (>10 min) or complicated instrument alignments (e.g., involving laser and cooled charge-coupled device) or other deficiencies.…”

We report a practical fluorescent sensor device for the trace amount detection of hydrogen peroxide vapor. In this paper, we have significantly improved the performance of fluorescence analysis for the detection of peroxides by solving the problems of packaging and storage of active materials and transferring the chemical experiment phenomenon to the actual project output. The fluorescent sensor molecule, test substrates, mixing methods, and the way to improve the life time are carefully studied. Combined with the design of circuit and programming, a field-test prototype was designed for peroxide explosives and its performance and algorithm were screened and optimized. In the detection of traces of H 2 O 2 generated by ultraviolet separation or leaked as inherent impurities, the high-efficiency and rapid detection of peroxide-based explosives is achieved. The detection limit of H 2 O 2 is expected to reach 2 ppb, and the response time can reach <0.5 s.
