In this work, we present a new metal organic framework Zn 7 (Ad) 4 (BTC) 4 (DMF)OÁ4DMAÁ3DMFÁ4H 2 O which was synthesized under hydrothermal conditions with adenine and trimesic acid (BTC) linkers. The structure was determined by single-crystal (XRD) and the compound was further characterized by Scanning electron microscopy (SEM), infrared spectroscopy (IR), and thermogravimetric analysis. The 3D anionic framework includes adenine present in two-different coordination modes, with dimethylammonium balancing the framework charge.
Metal-Organic Frameworks (MOFs) are a class of crystalline materials that, thanks to their large surface area and high porosity, allow them to be used in various areas of knowledge. This diversity of applications is due to the metal ions and the organic binders that compose them, but it is also important to highlight the ability of MOFs to function as hosts for a great variety of molecules of very different sizes and chemical properties. The first existing approaches for incorporating biomolecules in MOFs are discussed: pore encapsulation, surface binding, covalent binding, and in-situ encapsulation. Next, we discuss the obstacles of designing MOFs for effective gene delivery and how to enhance the gene delivery using different strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
