3D-printing metal-organic framework solids for high-pressure gas storage and separation

Metal-organic frameworks (MOFs) rank among the best materials for catalysis, gas storage and gas storage and processing. So far, more than 20 000 different MOFs have been fabricated and characterized. A crucial issue for designing MOF-based solids is about finding the best comprise between the material's porosity and its mechanical resistance in relation to a specific application. To do that, researchers have developed a modified 3D printer for the controlled deposition of inks, formulated from different MOF powders. This robocasting provides perfect control on the size and morphology of the final solid.

Metal-organic-framework-derived 2D carbon nanosheets for localized bacterial eradication and anti-infective therapy

The combination of multiple therapeutic modalities with synergetic effects is a promising approach to enhance antibacterial efficiency and possibly decrease the needed concentration of bactericidal reagents. In new work, scientists report a path to achieve efficient localized bacterial eradication and anti-infective therapy by combining the advantages of 2D graphene and metal organic framework (MOF)-derived carbon nanomaterials. This proposed MOF-derived 2D carbon nanosheets (2D-CNs) can form aggregations spontaneously under NIR irradiation and meanwhile exhibit localized triple bactericidal modalities.

Metal-organic frameworks as high-performance water desalination membranes

Reverse osmosis (RO) is one of the most effective desalination technologies for producing freshwater from seawater. The reverse osmosis membrane water reclamation processes is very energy intensive - not exactly an advantage given the rising cost of energy and the negative climate impact of fossil fuels. In a new study, researchers found that metal-organic frameworks (MOF) allow higher water flux compared to other 2D materials while rejecting almost 100% of unwanted ions.

MOF-encapsulated DNA for gene therapy

A critical challenge in gene therapy is the safe and effective delivery of genetic materials across cell membranes into target cells. Although viral systems have been the most effective method for delivering genetic matter into cells, they pose significant safety problems. Demonstrating a novel alternative delivery vector, researchers have developed a facile one-pot strategy to encapsulate plasmid DNA into nanoscale metal-organic frameworks (MOFs) and a MOF-polymer system Experiments showed that pDNA molecules could be well distributed throughout the MOF nanostructures and benefited from effective protection against the enzymatic degradation.
