“…In addition, MOF products have been successfully used in the adsorption of organic compounds. Therefore, more studies are necessary to assess the efficiency and nano-safety of these material types due to their versatility (51). A study conducted on the nanocarrier system had effectively delivered antitumor and retroviral anti-cancer and AIDS medication by non-toxic, porous iron (III) based MOFs (such as MIL-53, MIL-88, MIL-88Bt, MIL-89, MIL-100, and MIL-101 NH2) (52).…”

Background/Aim: Hypertrophic scars (HS) are an abnormal cutaneous condition of wound healing characterized by excessive fibrosis and disrupted collagen deposition. This study assessed the potential of a silicone patch embedded with chemically stable zirconium-based metal-organic frameworks (MOF)-808 structures to mitigate HS formation using a rabbit ear model. Materials and Methods: A silicone patch was strategically engineered by incorporating Zr-MOF-808, a composite structure comprising metal ions and organic ligands. Structural integrity of the Zr-MOF-808 silicone patch was validated using scanning electron microscopy and X-ray diffraction analysis. The animals were divided into three groups: a control, no treatment group (Group 1), a silicone patch treatment group (Group 2), and a group treated with a 0.2% loaded Zr-MOF-808 silicone patch (Group 3). HS suppression effects were quantified using scar elevation index (SEI), dorsal skin thickness measurements, and myofibroblast protein expression. Results: Histopathological examination of post-treatment HS samples revealed substantial reductions in SEI (34.6%) and epidermal thickness (49.5%) in Group 3. Scar hyperplasia was significantly diminished by 53.5% (p<0.05), while collagen density declined by 15.7% in Group 3 compared to Group 1. Western blot analysis of protein markers, including TGF-β1, collagen-1, and α-SMA, exhibited diminished levels by 8.8%, 12%, and 21.3%, respectively, in Group 3, and substantially higher levels by 21.9%, 27%, and 39.9%, respectively, in Group 2. On the 35th day post-wound generation, Zr-MOF-808-treated models exhibited smoother, less conspicuous, and flatter scars. Conclusion: Zr-MOF-808loaded silicone patch reduced HS formation in rabbit ear models by inducing the proliferation and remodeling of the wound healing process.

“…), showing in some cases high structural stability [ 15 , 16 ]. In addition, it has been reported that Co MOFs in some cases do not cause toxicity on microorganisms and exhibit a low cytotoxic effect towards in a liver cell line (LO2) [ 17 , 18 ]. For example, Ordaz et al [ 17 ], through microrespirometric studies on activated sludge in the presence of a cobalt-based organic metal compound (MOF-Co), found that this material did not inhibit oxygen consumption of the activated sludge.…”

The synthesis of a Co metal–organic framework assembled from 5,10,15,20-tetrakis((pyridin-4-yl)phenyl)porphyrin; TPhPyP) “Co-MTPhPyP” is reported. The TPhPyP ligand was synthesized via aldehyde condensation in 28% yield and characterized by 1H nuclear magnetic resonance (1H NMR), Fourier-transform infrared (FTIR), high-resolution mass spectrometry (HRMS), and UV-visible spectroscopy (UV-vis). Co-MTPhPyP was prepared by the solvothermal method from TPhPyP and CoCl2·H2O in 55% yield and characterized by X-ray powder diffraction (XRD), FTIR, thermogravimetric analysis (TGA), field-emission scanning electron microscopy with energy-dispersive X-ray (FESEM-EDS), X-ray photoelectron spectroscopy (XPS), and dynamic light scattering (DLS), showing a particle size distribution of 418 ± 58 nm. The sorption properties of the Co-MTPhPyP for the effective removal of Pb(II) and Cu(II) were evaluated in an aqueous medium and Cthe results showed uptake capacities of 383.4 and 168 mg of the metal g−1 after 2 h, respectively. Kinetic studies of Pb(II) adsorption by Co-MTPhPyP were adjusted to the pseudo-second-order model with a maximum adsorption capacity of 458.8 mg g−1 at 30 min of exposition.
