表面支撑的金属有机框架（MOF）薄膜在可行的科学应用中有着巨大的前景，特别是在传感器和电子设备中。然而，扩散缓慢、传质有限、电导率低等问题阻碍了mof的工业应用。在此，我们提出了一种基于一种美丽的自然景观的以雾凇为灵感的MOF薄膜。为了模拟雾状结构，我们比较并总结了天然生物矿化和电化学自组装MOF的内在相似性，并采用阳极诱导的方法制备了雾状结构的MOF结构。有趣的是，具有空间填充大-中-微孔的MOF薄膜在同时测定乳酸和葡萄糖方面表现出了优异的电化学传感性能，包括高灵敏度、优异的选择性和在大pH值范围内的宽线性范围。此外，该系统还可以作为生物功能人体汗液传感平台。我们的工作为深入研究仿生时间概念，探索具有更多样化功能的特定结构的mof开辟了新的视野。
Surface-supported metal-organic framework (MOF) films hold fantastic promises for viable scientific applications, particularly in sensors and electronic devices. However, slow diffusion, limited mass transfer, and low conductivity hinder the industrial application of MOFs. Herein, we propose a rime-inspired MOF film based on a kind of beautiful natural landscape. To mimic rime architecture, we compare and conclude the intrinsic similarity between natural biomineralization and electrochemical self-assembly of MOFs and used an anodic-induced approach to producing rime-structured MOF architecture. Interestingly, the MOF film with space-filling macro-meso-micropores exhibits remarkable electrochemical sensing performances for simultaneous determination of lactate and glucose, including high sensitivity, excellent selectivity, and a wide linear range in a wide range of pH values. Moreover, this rime-inspired system is able to be applied as a biofunctional human perspiration sensing platform. Our work opens a new horizon for poring on biomimetic rime concept to explore specifically structured MOFs with more diverse functionalities.
