“…Nanomaterials/hybrid materials with enzyme‐mimicking activities have been incorporated into colorimetric biosensors with improved stability, reproducibility, and reduced cost. Fe‐based nanomaterials, such as Prussian blue nanoparticles, MNPs, ZnFe 2 O 4 ‐reduced GO nanostructures, and Fe‐based MOF with excellent peroxidase‐mimicking activities, were adopted as novel nanozyme labels for Salmonella detection (Cheng et al., 2019; Farka et al., 2018; Park, Jeong, Kim, & Park, 2015; Wu, Duan, Qiu, Li, & Wang, 2017). Furthermore, Zheng et al.…”

Salmonella is one of the main causes of foodborne infectious diseases, posing a serious threat to public health. It can enter the food supply chain at various stages of production, processing, distribution, and marketing. High prevalence of Salmonella necessitates efficient and effective approaches for its identification, detection, and monitoring at an early stage. Because conventional methods based on plate counting and real‐time polymerase chain reaction are time‐consuming and laborious, novel rapid detection methods are urgently needed for in‐field and on‐line applications. Biosensors provide many advantages over conventional laboratory assays in terms of sensitivity, specificity, and accuracy, and show superiority in rapid response and potential portability. They are now recognized as promising alternative tools and one of the most on‐site applicable and end user–accessible methods for rapid detection. In recent years, we have witnessed a flourishing of studies in the development of robust and elaborate biosensors for detection of Salmonella in food. This review aims to provide a comprehensive overview on Salmonella biosensors by highlighting different signal‐transducing mechanisms (optical, electrochemical, piezoelectric, etc.) and critically analyzing its recent trends, particularly in combination with nanomaterials, microfluidics, portable instruments, and smartphones. Furthermore, current challenges are emphasized and future perspectives are discussed.

“…The enzyme‐linked immunosorbent assay (ELISA) is a biochemical assay widely used in the fields of biomedical diagnosis, environmental monitoring, and food safety (Farka et al., ). In a typical sandwich ELISA assay, the target analyte to be measured is first recognized through a specific reaction of antigen (analyte) and the capture antibodies immobilized in a ELISA plate (Figure Ai‐ii).…”

The public concerns about agrifood safety call for innovative and reformative analytical techniques to meet the inspection requirements of high sensitivity, specificity, and reproducibility. Enzyme‐mimetic nanomaterials or nanozymes, which combine enzyme‐like properties with nanoscale features, emerge as an excellent tool for quality and safety detection in the agrifood sector, due to not only their robust capacity in detection but also their attraction in future‐oriented exploitations. However, in‐depth understanding about the fundamental principles of nanozymes for food quality and safety detection remains limited, which makes their applications largely empirical. This review provides a comprehensive overview of the principles, designs, and applications of nanozyme‐based detection technique in the agrifood industry. The discussion mainly involves three mimicking types, that is, peroxidase, oxidase, and catalase‐like nanozymes, capable of detecting major agrifood analytes. The current principles and strategies are classified and then discussed in details through discriminating the roles of nanozymes in diverse detection platforms. Thereafter, recent applications of nanozymes in detecting various endogenous ingredients and exogenous contaminants in foods are reviewed, and the outlook of profound developments are explained. Evidenced by the increasing publications, nanozyme‐based detection techniques are narrowing the gap to practical‐oriented food analytical methods, while some challenges in optimization of nanozymes, diversification of recognition‐to‐signal manners, and sustainability of methodology need to conquer in the future.

In this section, we discussed the nanozymes composed of noble metal nanoparticles (Au, [12] Ag, [13] Pt, [14] Pd [15] ), metal oxide nanoparticles (Fe 3 O 4 , [16] γ-Fe 2 O 3 , [17] Cu 2 O, [18] CeO 2 , [19] V 2 O 5 , [20] MnO 2 [21] ) and other nanomaterials (Prussian blue, [22] graphene oxide [23] ) with catalytic behavior. We mainly focused on the nanoparticle synthesis, their catalytic mechanisms and activity regulation in this section.…”

Nanomaterials with enzyme‐mimicking behavior (nanozymes) have attracted a lot of research interest recently. In comparison to natural enzymes, nanozymes hold many advantages, such as good stability, ease of production and surface functionalization. As the catalytic mechanism of nanozymes is gradually revealed, the application fields of nanozymes are also broadly explored. Beyond traditional colorimetric detection assays, nanozymes have been found to hold great potential in a variety of biomedical fields, such as tumor theranostics, antibacterial, antioxidation and bioorthogonal reactions. In this review, we summarize nanozymes consisting of different nanomaterials. In addition, we focus on the catalytic performance of nanozymes in biomedical applications. The prospects and challenges in the practical use of nanozymes are discussed at the end of this Minireview.
