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.

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.

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.

In this paper, we summarize the research advances of ZIF-90 as a nanocarrier in anticancer therapy, biomedical imaging and other therapy for different diseases (Fig. 1) over the last five years and evaluate the opportunities and challenges that may be …

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.
