“…For example, blood glucose level is an indicator of diabetes: hyperglycemia and hypoglycemia, [190][191] blood lactate level can predict multiple system organ failure (MSOF) caused by septic shock 192 and ischemia and inadequate oxygenation 193 . Over the years, a number of enzyme-mimicking nanostructured materils 188,[193][194][195][196][197][198][199][200][201][202][203][204] have been used for the detection of glucose, 194-197, 202, 203 lactate, 193,[198][199]204 uric acids, 200 kanamycin, 188 and arsenet 201 . In this section, nanozyme based electrochemical sensor for glucose detection is briefly discussed.…”

“…However, if the reaction rate is too slow, particle aggregation may occur [36]. The synthesis of hollow copper sulfide nanocubes (h-CuS NCs) was conducted via the chemical reduction method [37]. The average particle size was 50 nm and the specific surface area was 57.84 m 2 •g −1 , which is larger than that of general solid CuS (34.76 m 2 •g −1 ).…”

The current review is devoted to nanozymes, i.e., nanostructured artificial enzymes which mimic the catalytic properties of natural enzymes. Use of the term “nanozyme” in the literature as indicating an enzyme is not always justified. For example, it is used inappropriately for nanomaterials bound with electrodes that possess catalytic activity only when applying an electric potential. If the enzyme-like activity of such a material is not proven in solution (without applying the potential), such a catalyst should be named an “electronanocatalyst”, not a nanozyme. This paper presents a review of the classification of the nanozymes, their advantages vs. natural enzymes, and potential practical applications. Special attention is paid to nanozyme synthesis methods (hydrothermal and solvothermal, chemical reduction, sol-gel method, co-precipitation, polymerization/polycondensation, electrochemical deposition). The catalytic performance of nanozymes is characterized, a critical point of view on catalytic parameters of nanozymes described in scientific papers is presented and typical mistakes are analyzed. The central part of the review relates to characterization of nanozymes which mimic natural enzymes with analytical importance (“nanoperoxidase”, “nanooxidases”, “nanolaccase”) and their use in the construction of electro-chemical (bio)sensors (“nanosensors”).

“…However, there have still been several important drawbacks for electrochemical enzyme biosensors, including high price, unsatisfactory reproducibility, and insufficient long‐term stability . To overcome these problems, electrochemical non‐enzymatic glucose sensors that mainly depend on the electrocatalytic oxidation of glucose by various nanostructured materials have exhibited considerable research interest and application attention for the detection of glucose …”

Electrochemical non-enzymatic sensors have great potential for prompt and efficient detection of glucose. Herein, a novel, highly efficient electrochemical non-enzymatic glucose sensor is reported that is based on ultrathin PdAg single-crystalline nanowires (NWs). Ultrathin PdAg NWs are fabricated by a facile one-pot aqueous synthesis through an in situ growth strategy with an amphiphilic surfactant as the template. A comparison of the activities of PdAg NWs with different compositional ratios and nanostructures shows that ultrathin Pd 2 Ag 1 NWs hold the best performance toward electrochemical detection of glucose with an operable sensitivity of 11.6 μA mM À 1 cm À 2 and a linear response range of 0.1-8 mM. Structural and compositional features of the Pd 2 Ag 1 NWs allow an excellent selectivity, rapid response, and good long-term stability for electrochemical glucose sensor. This work thus provides a new possibility for the rational design and synthesis of noble-metal-based nanomaterials for non-enzymatic sensors.[a] Dr.
