Light responsive metal-organic frameworks as controllable CO-releasing cell culture substrates.

چکیده
A new carbon monoxide (CO)-releasing material has been developed by embedding a manganese carbonyl complex, MnBr(bpydc)(CO)3 (bpydc = 5,5'-dicarboxylate-2,2'-bipyridine) into a highly robust Zr(iv)-based metal-organic framework (MOF). Efficient and controllable CO-release was achieved under exposure to low intensity visible light. Size-controllable nanocrystals of the photoactive MOF were obtained and their CO-releasing properties were correlated with their crystal sizes. The photoactive crystals were processed into cellular substrates with a biocompatible polymer matrix, and the light-induced delivery of CO and its subsequent cellular uptake were monitored using a fluorescent CO-probe. The results discussed here demonstrate a new opportunity to use MOFs as macromolecular scaffolds towards CO-releasing materials and the advantage of MOFs for high CO payloads, which is essential in future therapeutic applications.

Carbon Dioxide Capture on Metal-organic Frameworks with Amide-decorated Pores
CO2 is the main greenhouse gas emitted from the combustion of fossil fuels and is considered a threat in the context of global warming. Carbon capture and storage (CCS) schemes embody a group of technologies for the capture of CO2 from power plants, followed by compression, transport, and permanent storage. Key advances in recent years include the further development of ne...
متن کاملSurface anchored metal-organic frameworks as stimulus responsive antifouling coatings.
Surface-anchored, crystalline and oriented metal organic frameworks (SURMOFs) have huge potential for biological applications due to their well-defined and highly-porous structure. In this work we describe a MOF-based, fully autonomous system, which combines sensing, a specific response, and the release of an antimicrobial agent. The Cu-containing SURMOF, Cu-SURMOF 2, is stable in artificial se...

Metal-Organic Frameworks (MOFs) represent a new class of highly porous materials. On this regard, two nano porous metal-organic frameworks of [Zn2(1,4-bdc)2(H2O)2∙(DMF)2]n (1) and [Zn2(1,4-bdc)2(dabco)]·4DMF·1⁄2H2O (2), (1,4-bdc = benzene-1,4-dicarboxylate, dabco = 1,4-diaza...
متن کاملNovel Porous Iron Molybdate Catalysts for Synthesis of Dimethoxymethane from Methanol: Metal Organic Frameworks as Precursors
As a novel performance, methanol gas conversion to dimethoxymethane (DMM) in one-step based on Fe-Mo-O (iron molybdate mixed oxides) catalysts with high surface area fabricated by metal organic frameworks (MOFs) precursors was improved. For this approach, at first, Fe(III) precursors (iron (III) 1,3,5-benzenetricarboxylate (MIL-100 (Fe) and iron terephthalate (MOF-...
