“…The high cost and instability limit the use of enzyme sensors and a simple, reliable, sensitive and fast non‐enzyme sensor seems to be more promising in practical applications. In the construction of non‐enzyme H 2 O 2 biosensors, the substitution of enzyme is usually nanomaterials with electrocatalytic activity for H 2 O 2 , such as transition metallic nanoparticles (Au , Ag , Pd ,Pt and Cu ) and their alloys (AgCu, PdPt) and metal oxides (Fe 3 O 4 , CuO , Co 3 O 4 ).…”

In this study, a laser‐induced graphene (LIG) loaded platinum nanoparticles (PtNPs) was prepared for precise, rapid and non‐enzymatic electrochemical detection of hydrogen peroxide (H2O2). The commercial PI films were used as the substrate of LIG. In order to improve the electrochemical performance of LIG, a layer of PtNPs catalyst was fabricated through a magnetron sputtering process on the surface of LIG (PtLIG). Under optimized conditions, a linear relationship between H2O2 reduction current and H2O2 concentration was recorded, the correlation coefficient R2 is 0.9919 with the detection limit of 0.1 μM (S/N=3) and the sensitivity of 248.4 μA mM−1cm−2. Moreover, the PtLIG exhibits excellent selectivity, reproducibility and repeatability. Because of these remarkable advantages, we believe that PtLIG will provide a wider range of applications in biosensors and bioelectronic devices.

Electrochemical detection of hydrogen peroxide has achieved rapid development, due to the wide presence in industrial production, everyday life, bioprocess and green energy chemistry, etc. Many three‐dimensional structures have emerged as state‐of‐the‐art electrocatalysts due to their fascinating structures and electrochemical properties. This review summarizes free‐standing three‐dimensional electrocatalysts based on metal, metal oxide, carbon & silicon, and unconventional materials for detection of hydrogen peroxide with low limit of detection, wide range and fast response. The work also highlights their applications in near neutral conditions, especially their ability for single cell detection and mapping in biological environment. Further exploration into these materials together with devices design will facilitate the development of next‐generation detection technologies toward in situ and real‐time detection and contribute to wearable/portable smart detection electronics.

A non-enzymatic sensor for hydrogen peroxide (H 2 O 2) determination based on Ag/δ-FeOOH nanocomposite immobilized on an all-plastic disposable carbonbased electrochemical cell (DCell) is constructed by a rapid prototyping technique. Ag/δ-FeOOH is synthesized by a simple and reproducible method and its structural and morphological properties characterized by X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The Ag/δ-FeOOH is successfully immobilized on the DCell, as revealed by SEM images. The electrochemical investigation indicates that the Ag/δ-FeOOH/DCell has a good electrocatalytic response for the H 2 O 2 reduction, showing detection limit of 71 μmol L À 1 H 2 O 2 at a signal-tonoise ratio of 3 and analytical sensitivity of 215.4 μA mM À 1 cm À 2. Moreover, Ag/δ-FeOOH/DCell can be used to selectively detect H 2 O 2 in the presence of dopamine (DA), uric acid (UA), and ascorbic acid (AA). Finally, Ag/δ-FeOOH/DCell can be used to determine H 2 O 2 in fetal bovine serum. The achieved results indicate that the non-enzymatic Ag/δ-FeOOH/DCell is a costeffective alternative for the determination of H 2 O 2 .
