Researchers propose novel flexible Mn-doped zirconium metal-organic frameworks nanocubes for highly effective combination of microwave dynamic and thermal therapy against cancer. This is the first report of determining the microwave thermal conversion efficiency, which can be used to evaluate, compare, and predict the microwave sensitivity of different microwave-sensitive agents. More importantly, such Mn-ZrMOF nanocubes generate abundant reactive oxygen species of hydroxyl radicals under microwave irradiation.

Metal-organic frameworks (MOFs) are well-ordered, lattice-like crystals. The nodes of the lattices are metals, which are connected by organic molecules. Their size-controllable nanopores, special structure and large surface area make MOFs very attractive materials for next-generation, highly sensitive gas sensors. In new work, researchers demonstrate a process that can be used for developing low-cost and highly sensitive gas sensors. By increasing the sensitivity, the amount of gas sensitive material and device size can be reduced which in turn would reduce the overall cost of the device and energy consumption.

Molecular ferroelectrics are highly desirable as they are environmentally friendly, light-weight, and high spontaneous polarized. Though intensive studies have been focused on molecular ferroelectrics, very few researchers have tried to address the issue of thin film growth. An international research team now presents the first report on the preparation of high-quality large area MOFE films using in-plane liquid phase growth. With this approach, different kinds of novel ferroelectric films can be grown for potential practical applications such as temperature sensing, data storage, actuation, energy harvesting and storage.

With their special structure and large surface area, MOFs open up new opportunities in drug delivery. The ability to exchange the metal centers and organic linkers even provide an extensive library of MOF materials. As a result, the integration of small guest molecules within the MOF pores, such as small molecule drugs and biomolecules, have shown promise for delivery applications to treat diseases. A recent review article discusses current proceedings on integrating diverse biomolecules within MOFs.

Metal-organic frameworks (MOFs) are well-ordered, lattice-like crystals. The nodes of the lattices are metals, which are connected by organic molecules. The most impressive features of MOFs are their extremely high surface area, high porosity, and tunable pore sizes, which are remarkable advantages over other porous materials (e.g., zeolites and carbons). With their special structure and large surface area, MOFs open up new opportunities for alternative systems for gas and energy storage (e.g. carbon dioxide and hydrogen storage), in catalysis, chemical sensing, as nanoreactors, and in drug delivery, making them hugely interesting for both university research and industry.

Metal-organic frameworks (MOFs) are regarded as a new class of porous materials with significant prospects for addressing current challenges pertinent to energy and environmental sustainability. Due to their unique structure design and tunability, MOFs offer great potential for their effective integration and exploration in various sensing applications. Researchers have demonstrated this by developing an advanced sensor for the detection of hydrogen sulfide at room temperature, using thin films of rare-earth metal based MOF.
