Nanocrystals of ZIF-90 have been synthesized at room temperature through a novel procedure and incorporated into PBI-based nano-composite membranes for hydrogen purification. The physical and chemical structures of the ZIF-90 nanoparticles have been examined via multiple advanced instrumental analyses includ

2019年2月6日 · Here we report ATP-responsive zeolitic imidazole framework-90 (ZIF-90) as a general platform for cytosolic protein delivery and CRISPR/Cas9 genome editing. The self-assembly of imidazole-2-carboxaldehyde and Zn 2+ with protein forms ZIF-90/protein nanoparticles and efficiently encapsulates protein.

2020年5月13日 · ZIF － 90 由 ICA 与 Zn2＋构成最基本单元，其中每个Zn 原子与4个ICA 环上的 N 原子配位，形成了一个具有正四面体结构的ZnN 4 团簇，以这些团簇为节点，通过ICA 上的咪唑环相连接，构成了一个具有正六面体晶型的笼状配位化合物（见图 2 ）。

2022年8月1日 · PSM offered enhancement of ZIF-90 properties enabling acidic solutions stability and superior coordination capabilities of P=O and -NH 2 groups towards U (VI)/Th (IV) capture thereby leading to efficient sequestration. ZIFs showed facile desorption by lowering the pH and recyclability for two cycles.

2016年1月26日 · A superhydrophobic zeolitic imidazolate framework (ZIF-90) with high steam stability is prepared through post-functionalization via an amine condensation reaction. The developed superhydrophobic ZIF-90 is highly promising as an effective and reusable adsorbent for bio-alcohol recovery.

2024年10月21日 · We further applied zinc-imidazolate metal-organic framework-90 (ZIF-90) to encapsulate DzTAC (ZIF-90@DzTAC), facilitating its delivery into cancer cells while self-supplying Zn 2+ via adenosine triphosphate (ATP)-triggered ZIF-90 dissociation. Moreover, ZIF-90@DzTAC can enhance the treatment efficacy of doxorubicin-based chemotherapy in tumor ...

2024年8月6日 · The highly efficient, less toxic, low-cost and activation-free microwave synthesis resulted in the formation of ZIF-90 nanoparticles that exhibited the highest maximum water adsorption capacity (0.37 g/g) and the best hydrothermal stability between water adsorption at 30 °C and desorption at 100 °C at 12.5 mbar among all the products obtained.

2023年10月27日 · zif-90作为一种新型mof，在生物医药领域逐渐受到更多关注。zif-90具有比表面积大、孔结构均匀、生物相容性好等优点。重要的是，特定的ph/atp敏感性和线粒体靶向为其成为智能药物输送系统提供了机会。但不幸的是，很少有专门针对 zif-90 的评论。

基于zif-90颗粒与pva基质之间的交联反应，zif-90 / pva杂化膜表现出更高的机械强度，抗溶胀性和乙醇脱水的高分离性能。zif-90 / pva杂化膜通过扫描电子显微镜，x射线光电子能谱，傅立叶变换红外光谱，x射线衍射法，热重分析，机械测试和水接触角测量。

摘要 zif-90是一种沸石咪唑酯骨架材料,具有比表面积大、孔道结构均一、水热稳定性和化学稳定性高、易于修饰和合成简单等优点,可以广泛地应用于分离、吸附、催化、药物载药等领域。简单介绍了其合成方法和发展现状,结合不同应用领域的...
