“…The phenanthroline ligand and intermolecular hydrogen bonds that were formed might have been the cause of the MOF’s strong antimicrobial action. As a result, the MOF’s cationic release property made it a perfect bactericidal agent for antimicrobial medications. ,− Furthermore, the cobalt-ion-containing active centers of this MOF function as effective catalysts for lipid peroxidation of the plasmalemma’s bilipid layer, which ruptures the bacterial cell membrane and inactivates the bacterium. High and sustained antimicrobial activity is ensured by the nearly 100% catalyst recirculation used in the process …”

Metal–organic frameworks (MOFs) are a class of hybrid inorganic–organic materials with typical porous structures and a unique morphology. Due to their diversity, they are extensively used in a wide range of applications such as environmental, catalysis, biomedicine, etc. In this study, a novel cobalt-based MOF modified with tannic acid (Co-TPA/TA) (TPA: terephthalic acid; TA: tannic acid) as a promising material for antimicrobial agents was synthesized and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy with energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, inductively coupled plasma-optical emission spectrometry, and thermogravimetric analysis and compared with an as-synthesized cobalt-based framework. Co-TPA/TA demonstrated good antimicrobial efficiency under optimum conditions against yeast Candida albicans ATCC 10231, Gram-negative Escherichia coli ATCC 8739, and Gram-positive Staphylococcus aureus ATCC 6538 with an inhibition zone ranging from 14 to 20 mm. Reduced ATP levels, generation of reactive oxygen species, membrane damage from cobalt ion release, and development of an alkaline microenvironment could all be contributing factors to the possible antimicrobial pathways. The novel framework can be obtained using simple, affordable, and easily accessible commercial ligands and is considered to have the potential to be used as an antimicrobial material in the future.

“…[20][21][22] Furthermore, many studies have confirmed that MOFs can be efficiently incorporated into organic polymer films to form mixed matrix-membranes, selffolding films, and other types of functional films. [23][24][25][26][27] Interestingly, MOFs can be designed to undergo triggered release of adsorbed species via stimuli such as pH or light. [28][29][30] For example, a pH change that causes MOF degradation has been used to release hosted drugs (e.g., doxorubicin and artemisinin) from the well-known MOFs ZIF-8 and MIL-100(Fe).…”

Multidrug‐resistant bacteria have become a global health problem for which new prophylactic strategies are now needed, including surface‐coatings for hospital spaces and medical equipment. This work reports the preparation and functional validation of a metal‐organic framework (MOF) based composite for the triggered controlled release of iodine, an antimicrobial element that does not generate resistance. It comprises beads of the iodophilic MOF UiO‐66 containing encapsulated gold nanorods (AuNRs) coated with a silica shell. Irradiation of the AuNRs with near‐infrared light (NIR) provokes a photothermal effect and the resultant heat actively liberates the iodine. After validating the performance of this composite, it is integrated into a polymer for the development of antibacterial films. This work assesses the adsorption of iodine into these composite films, as well as its passive long‐term release and active light‐triggered. Finally, this work validates the antibacterial activity of the composite films in vitro against gram‐positive and gram‐negative bacteria. The findings will surely inform the development of new prophylactic treatments.
