“…The peroxidase‐like catalytic activity of these MNPs may depend on Fe 2+ , Fe 3+ , and M 2+ (M = Co, Zn, Mg, Ni, Cu, Mn) ions in solutions just like the Fenton's reagents which are known to catalyze the breakdown of H 2 O 2 to generate · OH . Moreover, the Fe 3 S 4 MNPs were also revealed to possess intrinsic peroxidase‐like activity …”

Diabetes is a dominating health issue with 425 million people suffering from the disease worldwide and 4 million deaths each year. To avoid further complications, the diabetic patient blood glucose level should be strictly monitored despite there being no cure for diabetes. Colorimetric biosensing has attracted significant attention because of its low cost, simplicity, and practicality. Recently, some nanomaterials have been found that possess unexpected peroxidase‐like activity, and great advances have been made in fabricating colorimetric glucose biosensors based on the peroxidase‐like activity of these nanomaterials using glucose oxidase. Compared with natural horseradish peroxidase, the nanomaterials exhibit flexibility in structure design and composition, and have easy separation and storage, high stability, simple preparation, and tunable catalytic activity. To highlight the significant progress in the field of nanomaterial‐based peroxidase‐like activity, this work discusses the various smart nanomaterials that mimic horseradish peroxidase and its mechanism and development history, and the applications in colorimetric glucose biosensors. Different approaches for tunable peroxidase‐like activity of nanomaterials are summarized, such as size, morphology, and shape; surface modification and coating; and metal doping and alloy. Finally, the conclusion and challenges facing peroxidase‐like activity of nanomaterials and future directions are discussed.

“…Peroxidase-like systems can be utilized in diverse areas of bioscience, medicine and environmental technology. New types of peroxidase-mimetic (nano)particles have been successfully employed as a component of biosensors for the detection of cancer (Tian et al 2015;Zheng et al 2016), glucose (Ding et al 2016), H 2 O 2 (Qiao et al 2014), heavy metal ions , cholesterol and pathogenic bacteria (Jiang et al 2016;Park et al 2015), as well as, for degradation of xenobiotics (Guo et al 2015;Mu et al 2016;Wan et al 2016), or for inhibition of bacterial growth and biofilm elimination .…”

Various materials have been extensively investigated to mimic the structures and functions of natural enzymes. We describe the discovery of a new catalytic property in the group of biochar-based carbonaceous materials, which are usually produced during biowaste thermal processing under specific conditions. The tested biochars exhibited peroxidase-like catalytic activity. Biomaterial feedstock, pyrolysis temperature, size of resulting biochar particles or biochar modification (e.g., magnetic particles deposition) influenced the peroxidase-like activity. Catalytic activity was measured with the chromogenic organic substrates N,N-diethyl-p-phenylenediamine (DPD) or 3,3′,5,5′-tetramethylbenzidine (TMB), in the presence of hydrogen peroxide. Magnetic biochar composite was studied as a complementary material, in which the presence of iron oxide particles enhances catalytic activity and enables smart magnetic separation of catalyst even from complex mixtures. The activity of the selected biochar had an optimum at pH 4 and temperature 32 °C; biochar catalyst can be reused ten times without the loss of activity. Using DPD as a substrate, K m values for native wood chip biochar and its magnetic derivative were 220 ± 5 μmol L −1 and 690 ± 80 μmol L −1 , respectively, while V max values were 10.1 ± 0.3 μmol L −1 min −1 and 16.1 ± 0.4 μmol L −1 min −1 , respectively. Biochar catalytic activity enabled the decolorization of crystal violet both in the model solution and the fish pond water containing suspended solids and dissolved organic matter. The observed biochar enzyme mimetic activity can thus find interesting applications in environmental technology for the degradation of selected xenobiotics. In general, this property predestines the low-cost biochar to be a perspective supplement or even substitution of common peroxidases in practical applications.

“…Diabetes mellitus is one of the most common non-communicable diseases globally, and its related complications result in increasing disability, reduced life expectancy, and enormous health costs for virtually every society. Therefore, the efforts to develop various sensors for fast and reliable glucose monitoring for the diagnosis of diabetes have received continuous interest, for which enzyme-based glucose sensors have been extensively explored [1][2]. Currently, glucose sensors have been fabricated basing on the use of two enzymes: glucose oxidase as specific enzyme (capture probes) and the second is peroxidase for signal measurement (signal probes).…”

In this work, we have developed a simple method for preparation of silver nanoparticles/graphene quantum dots hybrid (AgNPs/GQDs) using graphene quantum dots (GQDs) as reducing reagent and stabilizer. The synthesized GQDs and AgNPs/GQDs hybrid have been characterized by ultraviolet–visible spectroscopy (UV-Vis), photoluminescence (PL), X-ray diffraction (XRD) and transmission electron microscopy (TEM). Results indicated that mono-dispersed AgNPs were obtained with particles size around 30 nm. Based on the etching of silver nanoparticles by hydrogen peroxide (H2O2), we have constructed a colorimetric sensor for H2O2 and glucose sensors basing on the use of AgNPs/GQDs hybrid as capture probe and signal probe. The fabricated sensors performed excellent sensitivity and selectivity, high reproducibility for H2O2 and glucose detection with a low detection limit of 100 nM and 0.1 mM for hydrogen peroxide and glucose, respectively.
