| 1 | Recent progress in MOFs-based nanozymes for biosensing显示文摘Nanozymes are nanomaterials with enzyme-mimicking catalytic activity.Compared to natural enzymes,nanozymes show various properties such as easy to manufacture,stable,adjustable,and inexpensive.Nanozymes play key roles in biosensing,biocatalysis,and disease treatment.As an important kind of nanozymes,metal-organic framework(MOF)-based nanozymes are receiving a lot of attention due to their structural properties and composition.Rationally developing MOF with enzymes-like catalytic properties has opened new perspectives in biosensing.This review summarizes the up-to-date developments in synthesizing two-dimensional and three-dimensional MOF-based nanozymes and their applications in biosensing.Firstly,classification of nanozymes obtained by MOFs is categorized,and different properties of MOF-based nanozymes are described.Then,the distinctive applications of MOF-based nanozymes in identifying various analytes are thoroughly summarized.Finally,the recent challenges and progressive directions in this area are highlighted. | Imamdin Chandio Yongjian Ai Lei Wu Qionglin Liang | 2024 | Nano Research2024，17，1： | 0 |
| 2 | 纳米酶构效关系及其在食品检测中的应用显示文摘天然酶具有较高的催化活性和底物特异性,但有成本高、运行稳定性低、回收困难等不足。纳米酶是一种具有类酶活性的纳米材料,由于具有可设计、活性可控、耐环境等优异性能,逐渐成为天然酶的有力竞争者和潜在替代品。纳米酶的催化过程与天然酶有所不同,纳米酶的活性与其大小、表面晶格、表面修饰、组成等密切相关。纳米酶在食品检测方面的应用,解决了传统检测方法需要烦琐的预处理步骤、昂贵的仪器、专业的技术人员和长的检测周期等不足。然而,目前基于纳米酶的大多数检测方法难以保证对目标检测物的灵敏性,且纳米酶在催化活性方面较天然酶还需要进一步提高。本文对纳米酶的结构和催化活性的关系及纳米酶在食品中重金属离子、添加剂、生物毒素、农药残留、抗生素等检测方面的应用进行综述,并对该领域未来发展前景进行展望,为纳米酶在食品安全检测中的更深入的应用提供参考。 | 张卫丹 辛嘉英 贺姣 徐景懿 夏春谷 | 2023 | 食品安全质量检测学报2023，14，19： | 0 |
