Metal-organic framework MOF membranes are potentially useful in gas separation applications, but conventional methods for preparing MOF membranes are multi-steps and under high-pressure synthetic conditions. The enhanced separation performance obtained in this study has been the highest so far among other supported pure ZIF-8 membranes, which can be attributed to the defect-free and thermally stable ZIF-8 membranes.

Huai H. Varela-Guerrero, G. Furthermore, they zif 8 that the fibrous ZIF-8 aerogels also combined the hierarchical porosities and low density of cellulose aerogels, and hence this combination resulted in improved adsorption capacity and kinetics.

China E-mail: chunshengwu ZIF-8 nanoparticles were prepared with a convenient method at room temperature. The ZIF-8 nanoparticles were relatively stable under neutral and alkaline solutions, while their structure easily collapsed partially in the strong acidic aqueous solution. The adsorption kinetics and isotherms of ZIF-8 for tetracycline were evaluated in detail. The effects of key parameters such as pH, contact time, temperature and ionic strength on the adsorption of tetracycline were studied.

The biomedical application of metal—organic frameworks in cancer theranostics has become a research hotspot with rapid progress. As a typical representative, ZIF—8 attracts increasing interest from researchers due to its good performance and potential. In this review, we updated recent discoveries on the ZIF—8—based nanoplatforms for cancer, discussed the problems in current research and the obstacles for clinical translation of ZIF—8, and also proposed an outlook on its future development. Cancer severely threatens human health and has remained the leading cause of disease—related death for decades.

Metal—organic frameworks have the properties of high porosity, variable pore sizes, and easy modification as drug delivery systems. This review introduces the preparation and functional modification of ZIF-8, and its application in drug delivery, focusing on the single-stimulus and multi-stimulus response release of drugs in ZIF-8 materials, the integrated role of diagnosis and treatment with ZIF-8 in cancer treatment, and its application in the synergistic therapy of multiple cancer treatment methods. We summarize the latest developments of ZIF-8 in the field of drug delivery and tumor therapy, and present the main challenges that remain to be resolved in the ZIF-8 drug delivery system. Wang, Y.

Basu, A. They explained that this improvement was due to the synergistic effect of carbon nitride C 3 N 4 , which contributed to the regulation of the ZIF-8 crystal growth, leading to small and highly dispersed ZIF-8, resulting in a better performance for the removal of MB.

As a new kind of porous material, zeolitic imidazolate frameworks ZIF-8 are built from zinc ions and 2-methylimidazolate and possess unique merits including high porosity, good structural regularity and tunability, adjustable surface functionality and intrinsic pH induced biodegradability. These advantages endow ZIF-8 with multiple functionalities and stimuli-responsive controlled release of loaded payloads by endogenous or exogenous means. In this review, we will summarize the recent advancement of ZIF-8 as nanocarriers for the loading of various molecules including chemotherapeutic drugs, photosensitizers, photothermal agents, and proteins to fabricate multifunctional nanocomposites for synergistic cancer therapy.

Wang, A. Importantly a reduction in weight loss is associated with the free linker within the gallery spaces of ZIF-L. Hermes, F. Wang B. Hara, M. The heat treatment at 1. Adams, C. RSC Adv. In this work, the hetero-polyanion-based guanidinium ionic liquids HPAILs not only functioned as greener agents to effectively monitor the nucleation and growth rate of ZIF-8s, but were also embedded as a shell material for the creation of specific adsorption sites.
