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.

“…IR bands at around 3500 cm −1 , 1620 cm −1 and 1450 cm −1 may be attributed to the stretching, bending and in‐plane bending modes of surface bound water molecules, respectively . In the FTIR spectrum of Mag@C, two small peaklets observed at around 2830 cm −1 and 2950 cm −1 are ascribed to stretching modes of CH 2 moieties while as a prominent peak at around 1120 cm −1 is ascribed to C−O stretching modes of hydroxyl bound carbon coated magnetite …”

Nanoparticles have earned huge research interest due to their well known characteristics such as high specific surface, minimal environmental impact, ease in surface modification and low solubility in water. As a result, such materials have been used effectively to remove toxic metal ions from wastewater. Their adsorption potential has been further improved by modifying their surfaces by various means. In one such attempt, we have successfully synthesized magnetite and modified its surface by carbon while using glucose carbonization method. The as‐synthesized carbon coated magnetite (Mag@C) composite was characterized by Fourier transform infrared (FTIR) spectroscopy and the results were further supported by Energy dispersive X‐ray spectrometry (EDX), Scanning electron microscopy (SEM), Thermal gravimetric analysis (TGA), Zetastudies and X‐ray diffraction crystallography (XRD) like techniques. The Adsorption properties of Mag@C were explored for the removal of Cd2+ and Pb2+ ions where a promising adsorption performance towards these metal ions with maximum adsorption capacities of 127.3 mg/g and 103 mg/g for Cd2+ and Pb2+ ions, respectively, was obtained. The material was also examined for its antifungal properties towards Aspergillus niger and Penicillium notatum, two toxic species of fungi and a good fungicidal property of the composite material was observed. Adual application of Mag@C makes it as a useful material in the process of waste water treatment.

“…For instance, the detection limit of glucose by Fe 3 O 4 NPs coated by carbon was 2 mM. 26 The DNA-nanoceria conjugates 7 and carbon NPs 24 allow the detection of only 8.9 and 20 mM glucose respectively. The obtained results can improve the analytic performance of glucose determination using articial mimics.…”

Artificial enzymatic mimics based on nanoparticles have become a powerful tool for the improvement of analytical performance in the detection of important bioactive compounds. For the first time the intrinsic peroxidase-like activity of Fe-core/carbon shell nanoparticles (Fe@C NPs) was studied. The catalytic process was described by a typical Michaelis-Menten curve for enzyme kinetics, and the results were comparable with those previously published. The high catalytic performance of the Fe@C NPs allows the development of a new simple procedure for glucose determination with a low detection limit of 0.21 mM. To our knowledge, this is the first study showing the ability to generate active oxygen species on the Fe@C surfaces. We suppose that our investigation will open up a new direction in medicinal applications using these promising materials.
