“…Subsequently, P-CDs-based P-CDs/ PVA films were designed as nanozyme-based food packaging to extend the storage period of strawberries and bananas. Qu et al 82 successfully synthesized a single-layer graphene carbonnitrogen-doped copper biomimetic system Cu 2+ -C 3 N 4 , which combines glucose sensing and antibacterial properties. The nanoparticles can mimic the catalytic activity of glucose oxidase, accelerating glucose oxidation and increasing H 2 O 2 production under visible light irradiation.…”

During the transportation and storage of food, foodborne spoilage caused by bacterial and biofilm infection is prone to occur, leading to issues such as short shelf life, economic loss, and sensory quality instability. Therefore, the development of novel and efficient antibacterial agents capable of efficiently inhibiting bacteria throughout various stages of food processing, transportation, and storage is strongly recommended by researchers. The emergence of nanozymes is considered to be an effective candidate for inhibiting foodborne bacteria agents in the food industry. As potent antibacterial agents, nanozymes have the advantages of low cost, high stability, strong broad-spectrum antibacterial ability, and biocompatibility. Herein, we aim to summarize the classification status of various nanozymes. Furthermore, the general catalytic bacteriostatic mechanism of nanozymes against intracellular bacteria, planktonic bacteria, and biofilm activities are highlighted, mainly concerning the destruction of cell walls and/ or membranes, reactive oxygen species regulation, HOBr/Cl generation, damage of intracellular components, and so forth. In particular, the review focuses on the pivotal role of nanozymes as antibacterial agents and delivery vehicles in the fields of food preservation applications. We look forward to the future prospects, especially in the field of food preservation, to promote broader applications based on antimicrobial nanozymes.

To promote rural revitalization under the premise of fully considering the ecological risk factors of land consolidation, this study takes A County in Shaanxi Province as a case study and introduces Self-Organizing Feature Map (SOFM) neural network and Internet of Things (IoT) technology to partition the land. In this study, a comprehensive index system is constructed based on IoT technology, and the relevant factors are quantitatively analyzed from the perspective of land consolidation ecological risk. Then, the land consolidation project area's attribute and geographic space domains are used as the input of the SOFM neural network to reveal the distribution and influence degree of each factor in the area and determine the zoning pattern of land consolidation in A County. The results show that the rural revitalization land zoning pattern of land consolidation in A County, Shaanxi Province, is divided into four land consolidation areas. Firstly, the priority remediation area soon covers 27 administrative villages with a total area of 28090 hm 2 , accounting for 32.75%. Secondly, the moderate renovation area is soon classified into 37 administrative villages, with a total area of 15986 hm 2 , equivalent to 18.55%. In the medium term, the land-saving renovation area covers 39 administrative villages with a total area of 19686 hm 2 , accounting for 22.75% of the total area. Finally, in the long-term restricted remediation area, 37 administrative villages are divided, with a total area of 22081 hm 2 , accounting for 25.67% of the total area. These data results provide a quantitative basis for land consolidation planning in this area to achieve the goal of rural land revitalization in different time ranges. This study is significant for implementing land consolidation projects in rural revitalization and provides a valuable reference for developing other similar areas.

Rhodium single-atom nanozymes (Rh SANs), mimicking the function of natural glucose oxidase (GOD) for both biometabolism and electrometabolism of glucose oxidation, were designed in this work. Here, Rh SANs were proved to have the same biocatalytic mechanism as natural GOD, as well as a similar electrocatalytic path, namely two-electron electrooxidation from glucose to gluconic acid. On this basis, by coupling a bilirubin oxidase (BOD) biocathode, the Rh SANs-based glucose/O2 enzymatic biofuel cell (EBFC) was developed, and a maximum power density of 135.0 ± 3.0 μW cm–2 was obtained, which was nearly 2-fold enhanced over that of natural GOD-based EBFC. In addition to gathering fuels from soft drinks available in daily life, this EBFC could be designed as a novel, low-cost, and miniaturized bio-energy device. With an ingenious catalyst and flexible configuration, the device not only accelerates the development of nanozymes but paves avenues for powering portable and wearable devices.
