“…Nanozymes have shown unique physical characteristics that enzymes do not possess, such as color absorption and photothermal effects. , For example, nanozymes have been exploited for improving the detection sensitivity of lateral flow immunoassay (LFIA) by using their enzyme-mimicking activity . Although enzymes possessed catalytic activity to enhance the sensitivity of this method, the lack of color absorption of the enzyme restrained its applicability in LFIA . Therefore, the utilization of nanozyme showed great potential to substitute for enzyme in the sensing of agroproducts.…”

“…Nanozymes, artificial nanoengineered nanocatalysts, are nanomaterials with enzyme-like properties that have longer-term stability and higher environmental endurance than their natural counterparts. , Since the first discovery of ligand functionalized gold nanoparticles (NPs) with ribonuclease-like activities in 2004, nanozymes have been clearly defined and gained the interest of researchers owing to their intrinsic catalytic activities, such as peroxidase-like (POD-like), oxidase-like (OXD-like), catalase-like (CAT-like), superoxide dismutase-like (SOD-like), and laccase-like (LAC-like) activities . Recently, nanozymes have appealed to the immense interest of the agricultural community owing to their catalytic diversity, reproducibility, economical friendliness, biosafety, and environmental stability. , Therefore, nanozymes are expected to exhibit good agricultural sustainability compared with traditional agrochemicals .…”

With the concept of sustainable agriculture receiving increasing attention from humankind, nanozymes, nanomaterials with enzyme-like activity but higher environmental endurance and longer-term stability than natural enzymes, have enabled agricultural technologies to be reformative, economic, and portable. Benefiting from their multiple catalytic activities and renewable nanocharacteristics, nanozymes can shine in agricultural scenarios using enzyme engineering and nanoscience, acting as sustainable toolboxes to improve agricultural production and reduce the risk to agricultural systems. Herein, we comprehensively discuss the classifications of nanozymes applied in current agriculture, including peroxidase-like, oxidase-like, catalase-like, superoxide dismutase-like, and laccase-like nanozymes, as well as their biocatalytic mechanisms. Especially, different applications of nanozymes in agriculture are deeply reviewed, covering crop protection and nutrition, agroenvironmental remediation and monitoring, and agroproduct quality monitoring. Finally, the challenges faced by nanozymes in agricultural applications are proposed, and we expect that our review can further enhance agricultural sustainability through nanozymology.

“…Nanozymes have emerged as a powerful substitute for enzymes in the application of food contamination detection, which have the advantages of low cost, high stability, and easy scale‐up in preparation compared with natural enzymes (Huang, Ren, et al., 2019; Li, Liu, et al., 2022). Interestingly, the intrinsic enzyme‐mimicking activity occurs in numerous nanomaterials, containing metal nanoparticles (NPs) (Pt, Ag, Au, Pd, Co, Fe, and Cu), metal oxides NPs (Fe 3 O 4 , CeO 2 , CuO, and MnO 2 ), metal chalcogenides (VS 2 , MoS 2 , and CuS), metal–organic framework (MOF), carbon‐based nanomaterials (graphene, nanotube, fullerenes, and nanodots), and nanocomposites.…”

With the rapid growth in global food production, delivery, and consumption, reformative food analytical techniques are required to satisfy the monitoring requirements of speed and high sensitivity. Nanozyme-encoded luminescent detections (NLDs) integrating nanozyme-based rapid detections with luminescent output signals have emerged as powerful methods for food safety monitoring, not only because of their preeminent performance in analysis, such as rapid, facile, low background signal, and ultrasensitive, but also due to their strong attractiveness for future sensing research. However, the lack of a full understanding of the fundamentals of NLDs for food safety detection technologies limits their further application. In this review, a systematic overview of the mechanisms of NLDs and their applications in the food industry is summarized, which covers the nanozyme-mimicking types and their luminescent signal generation mechanisms, as well as their applications in monitoring common foodborne contaminants. As demonstrated by previous studies, NLDs are bridging the gap to practical-oriented food analytical technologies and various opportunities to improve their food analytical performance to be considered in the future are proposed.

“…Since its first usage in the pregnancy test in 1970s, LFA has showed its success of the general design and kept almost unchanged (Parolo, de la Escosura‐Muñiz, & Merkoçi, 2013 ; Zhou, Wu, Ding, Huang, & Xiong, 2021 ). Almost all LFA strips rely on capillary forces for moving the sample and reagent along a test strip to produce a detectable signal (Yuechun Li et al., 2022 ; S. Liu, R. Shu, C. Nie, et al., 2022 ). Especially, LFA as a well‐known technology and a popular POC test platform have played a significant role in the control of the COVID‐19 pandemic (S. Liu, R. Shu, J. Ma, et al., 2022 ; Parolo et al., 2020 ; X. Zhang, Li, Wu, Liu, & Wu, 2020 ; Zhou et al., 2021 ).…”

The ongoing coronavirus disease 2019 (COVID‐19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has caused great public health concern and has been a global threat due to its high transmissibility and morbidity. Although the SARS‐CoV‐2 transmission mainly relies on the person‐to‐person route through the respiratory droplets, the possible transmission through the contaminated cold‐chain food and packaging to humans has raised widespread concerns. This review discussed the possibility of SARS‐CoV‐2 transmission via the contaminated cold‐chain food and packaging by tracing the occurrence, the survival of SARS‐CoV‐2 in the contaminated cold‐chain food and packaging, as well as the transmission and outbreaks related to the contaminated cold‐chain food and packaging. Rapid, accurate, and reliable diagnostics of SARS‐CoV‐2 is of great importance for preventing and controlling the COVID‐19 resurgence. Therefore, we summarized the recent advances on the emerging clustered regularly interspaced short palindromic repeats (CRISPR)/Cas system‐based biosensing technology that is promising and powerful for preventing the possible COVID‐19 resurgence caused by the contaminated cold‐chain food and packaging during the COVID‐19 pandemic, including CRISPR/Cas system‐based biosensors and their integration with portable devices (e.g., smartphone, lateral flow assays, microfluidic chips, and nanopores). Impressively, this review not only provided an insight on the possibility of SARS‐CoV‐2 transmission through the food supply chain, but also proposed the future opportunities and challenges on the development of CRISPR/Cas system‐based detection methods for the diagnosis of SARS‐CoV‐2.
