“…Metal–organic frameworks are a class of compounds that consist of inorganic and organic secondary building units (SBUs) bonded together to form a three-dimensional extended lattice with potential voids [ 19 , 20 ]. MOFs have attracted great attention since they were first reported, approximately two decades ago, particularly due to their porous structures and ultrahigh surface area, which makes them attractive for various applications, such as gas storage, separation, catalysis, and energy storage [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. The SBUs of MOFs are formed of metal ions or polymetallic cluster nodes and organic linkers, sometimes called “struts”.…”

Metal–Organic Frameworks and Their Biodegradable Composites for Controlled Delivery of Antimicrobial Drugs

Antimicrobial resistance (AMR) is a growing global crisis with an increasing number of untreatable or exceedingly difficult-to-treat bacterial infections, due to their growing resistance to existing drugs. It is predicted that AMR will be the leading cause of death by 2050. In addition to ongoing efforts on preventive strategies and infection control, there is ongoing research towards the development of novel vaccines, antimicrobial agents, and optimised diagnostic practices to address AMR. However, developing new therapeutic agents and medicines can be a lengthy process. Therefore, there is a parallel ongoing worldwide effort to develop materials for optimised drug delivery to improve efficacy and minimise AMR. Examples of such materials include functionalisation of surfaces so that they can become self-disinfecting or non-fouling, and the development of nanoparticles with promising antimicrobial properties attributed to their ability to damage numerous essential components of pathogens. A relatively new class of materials, metal–organic frameworks (MOFs), is also being investigated for their ability to act as carriers of antimicrobial agents, because of their ultrahigh porosity and modular structures, which can be engineered to control the delivery mechanism of loaded drugs. Biodegradable polymers have also been found to show promising applications as antimicrobial carriers; and, recently, several studies have been reported on delivery of antimicrobial drugs using composites of MOF and biodegradable polymers. This review article reflects on MOFs and polymer–MOF composites, as carriers and delivery agents of antimicrobial drugs, that have been studied recently, and provides an overview of the state of the art in this highly topical area of research.

“…Antibiotics are important medicines that are frequently prescribed to humans, animals, and plants in order to recover from infection and illness . However, the long-time consumption of antibiotics leads to resistance to antibiotic activity, which is even more harmful. , On the other hand, mismanagement of antibiotics can lead to the deposition of their residue in water and soil and finally impact our ecosystem . With the rise in the population, the intake of antibiotics and their misuse are the major concerns.…”

A fluorescent zinc-based two-dimensional (2D) coordination polymer, {[Zn(cis-CHA)(BPEP)0.5]•DMF}n (ZCP), has been synthesized using solvothermal reaction conditions. ZCP is characterized using singlecrystal X-ray diffraction, powder X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetric study, and elemental analysis. In waterdispersed medium, the framework (ZCP) detects antibiotics, such as nitrofurantoin (NFT) and nitrofurazone (NZF), as well as an organo-toxin aromatic compound, trinitrophenol (TNP). The limit of detection (LOD) values for NFT, NZF, and TNP are found to be 21.75, 24.31, and 13.47 ppb, respectively. Such sensing behavior is also apprehended by colorimetric response in solid and solution along with a strip paper method. After sensing of each and individual analytes, the sensor is recycled without losing its efficiency. Interestingly, the detection of these analytes by this sensor is also comprehended for real-field analysis with high accuracy and repeatability. The sensing behavior is strongly supported by profound experimental investigation, including the lifetime measurement, and the mechanism of sensing is well supported by theoretical calculations.

“…Metal Organic Frameworks (MOFs) are well-known crystalline porous materials based on metal ions or clusters coordinated to organic linkers following the principle of reticular chemistry [ 1 , 2 ]. MOFs can be found in the medical, environmental, energy, agricultural, textile, and food industries [ 3 , 4 , 5 , 6 ]. They are characterized by high surface areas, tunable pore size and functionalities, as well as physical–chemical stabilities.…”

A Straightforward Method to Prepare MOF-Based Membranes via Direct Seeding of MOF-Polymer Hybrid Nanoparticles

Metal Organic Frameworks (MOFs) present high surface areas, various pore topology as well as good stabilities. The functionalities and porosity can be tuned by using different linkers with various functional groups and a wide range of linker lengths. These properties make them good candidates in membrane separation applications. In this work, we propose a simple UiO-66 MOF-based membrane fabrication method following two steps. First, the α-alumina tubular membrane support was dip-coated with MOF-polymer hybrid nanoparticles (NPs). These NPs were prepared via one-pot synthesis by adding poly (methacrylic acid)-b-poly (methyl methacrylate) (PMAA-b-PMMA) NPs to the classical acetic acid-modulated UiO-66 or UiO-66-NH2 synthesis formulation. Second, secondary membrane growth was applied to give rise to a continuous and homogeneous crystalline MOF membrane layer. The gas permeances (He, N2, CO2 and SF6) tests confirmed high membrane permeability with no macro-defects. The as-prepared membranes that were used for dye separation (Rhodamine B) showed relatively good separation capacity.
