“…In the case of the nanostructure enzyme mimetics, the K m value is oen used to compare the enzyme-like performance of the nanoparticles. The K m value of Ru NPs with TMB as the substrate is higher than that of Ru frames, 49 It is also obvious that the oxidase-like activity of Ru NPs was much lower than its HRP-like activity.…”

“…Recently, Ru nanoframes are found to show peroxidase-like properties for the rst time. 49 Very recently, our group reported that Ru NPs have catalase-like and superoxide dismutase-like activities by scavenging hydrogen peroxide and superoxide, which may play important roles in maintaining redox balance in living organisms by scavenging excess reactive oxygen species. 50 In this work, we discovered that Ru NPs possess intrinsic HRP-like and oxidase-like mimetic activities.…”

“…The enhanced peroxidase‐like efficiency of Pt hollow nanodendrites could be ascribed to their enlarged surface area, given that a hollow nanostructure has both inner and outer surfaces. Similarly, our group reported Ru nanoframes (RuNFs) as a type of efficient peroxidase mimics . The RuNFs were synthesized through the overgrowth of Ru on Pd seeds followed by selective etching of Pd.…”

Noble‐metal nanostructures have emerged as a category of efficient and versatile peroxidase mimics in recent years. Enhancing their peroxidase‐like activities is essential to the realization of certain applications. In this review, we focus on how to engineer noble‐metal nanostructures with enhanced peroxidase‐like activities. The article is organized by introducing the impacts of surface capping ligands, particle size, shape, elemental composition, and internal structure as key parameters for the peroxidase‐like activity of noble‐metal nanostructures. Emphasis is given to the controlled synthesis of nanostructures and their peroxidase‐like catalytic efficiencies. At the end, we provide a perspective on future developments in the research relevant to peroxidase mimics of noble metals.

“…In another strategy, avidin-functionalized MWCNTs were decorated with ruthenium nanoparticles to prepare a multifunctional electrochemical interface on glassy carbon electrodes. The peroxidase-like properties of Ru [ 131 ] produced a synergic effect when combined with CNTs on the non-enzymatic catalytic reduction of H 2 O 2 over a wide linear range from 0.5 μM to 1.75 mM. The resulting nanomaterial allowed the anchoring of biotinylated glucose oxidase for the preparation of a glucose biosensor which was applied to the analysis of commercial beverages [ 96 ].…”

Multifunctional nanomaterials, defined as those able to achieve a combined effect or more than one function through their multiple functionalization or combination with other materials, are gaining increasing attention in the last years in many relevant fields, including cargo targeted delivery, tissue engineering, in vitro and/or in vivo diseases imaging and therapy, as well as in the development of electrochemical (bio)sensors and (bio)sensing strategies with improved performance. This review article aims to provide an updated overview of the important advances and future opportunities exhibited by electrochemical biosensing in connection to multifunctional nanomaterials. Accordingly, representative aspects of recent approaches involving metal, carbon, and silica-based multifunctional nanomaterials are selected and critically discussed, as they are the most widely used multifunctional nanomaterials imparting unique capabilities in (bio)electroanalysis. A brief overview of the main remaining challenges and future perspectives in the field is also provided.
