“…Yet, solvent-free approaches for patterning are currently at the forefront of technological needs due to their great potential in improving wafer processing efficiency and patterning quality at reduced material and energy cost 32 . Although solvent-free MOF deposition steps have been incorporated in lift-off patterning 33,34 , fully solvent-free bottom-up patterning of MOFs will further facilitate their application in microfabrication processes.…”

Patterning metal-organic frameworks (MOFs) at submicrometer scale is a crucial yet challenging task for their integration in miniaturized devices. Here we report an electron beam (e-beam) assisted, bottom-up approach for patterning of two MOFs, zeolitic imidazolate frameworks (ZIF), ZIF-8 and ZIF-67. A mild pretreatment of metal oxide precursors with linker vapor leads to the sensitization of the oxide surface to e-beam irradiation, effectively inhibiting subsequent conversion of the oxide to ZIFs in irradiated areas, while ZIF growth in non-irradiated areas is not affected. Well-resolved patterns with features down to the scale of 100 nm can be achieved. This developer-free, all-vapor phase technique will facilitate the incorporation of MOFs in micro- and nanofabrication processes.

“…For weak interactions between adjacent layers, the original 3D structure can be transformed into a 2D structure by exfoliation through ultrasound, vibration, and mechanics. [84][85][86] Especially in the preparation of MOF nanosheets, the top-down MOF nanosheet preparation method is less limited and more applicable compared with other methods.…”

Nanoscale/microscale metal–organic frameworks (nano/microscale MOFs) are considered kinds of nanomaterials with profound application potentials in many fields due to the high specific surface area, permanent porosity, and multiple chemical functions. This review focuses on the specific synthesis strategies of nano/microscale MOFs, such as controlled mediation, template, one‐pot, and interface growth methods, through which the shape and size of the crystal can be regulated during the nucleation process. After these targeted design and synthesis strategies, nano/microscale MOFs are optimized for energy storage, catalysis, and biomedical applications based on several merits, including a large specific surface area with more active sites, smaller ion transfer resistance, and structural stability. In addition, challenges and prospects of nano/microscale MOF materials are summarized for advanced energy storage and conversion applications.

“…Integration of MOFs with flexible electronic devices may start with downsizing MOFs particles into micro/nano-particles, which not only can preserve the same pore structures and surface reactivity as the bulky materials, but also can achieve MOFs thin films that match the mechanical properties of flexible electronics. The downsizing methods can be categorized into top-down and bottom-up approaches [363][364][365][366][367].…”

Metal-organic frameworks (MOFs) exhibit attractive properties such as highly accessible surface area, large porosity, tunable pore size, and built-in redox-active metal sites. They may serve as excellent candidates to construct implantable flexible devices for biochemical sensing due to their high thermal and solution stability. However, MOFs-based sensors have only been mostly reported for in-vitro chemical sensing, their use in implantable chemical sensing and combination with flexible electronics to achieve excellent mechanical compatibility with tissues and organs has rarely been summarized. This paper systematically reviews the biochemical sensors based on MOFs and discusses the feasibility to achieve implantable biochemical sensing through MOFsbased flexible electronics. The properties of MOFs and underlying mechanisms have been introduced, followed by a summarization of different biochemical sensing applications. Strategies to integrate MOFs with flexible devices have been supplied from the standpoints of matching mechanics and compatible fabrication processes. Issues that should be addressed in developing flexible MOFs sensors and potential solutions have also been provided, followed by the perspective for future applications of flexible MOFs sensors. This paper may serve as a reference to offer potential guidelines for the development of flexible MOFs-based biochemical sensors that may benefit future applications in personal healthcare, disease diagnosis and treatment, and fundamental study of various biological processes.
