“…In the FT-IR spectra of Cu/DPA-MOF and Cu/DPA-MOF/OP/CS hydrogel, significant absorptions such as Cu–O, C–O, C=C, C=N, and C=O were observed in regions 400–600 cm -1 ( Elango et al, 2018 ), 1000–1100 cm -1 , 1300–1400 cm -1 , 1450 cm -1 , and 1600 cm -1 , respectively. In the FT-IR spectrum of Cu/DPA-MOF/OP/CS hydrogel, absorption related to C–H of SP 3 carbons below 3000 cm -1 and O–H groups in the region of 3300 cm -1 were observed ( Bakhshi et al, 2022 ; Jasim et al, 2022 ).…”

Today, with the indiscriminate use of antibiotics, we face the resistance of some bacterial strains against some antibiotics. Therefore, it is essential to report and synthesize new compounds with antimicrobial properties. A novel copper/dipicolinic acid–metal–organic framework cross-linked oxidized pectin and chitosan (Cu/DPA-MOF/OP/CS) hydrogel polymer was synthesized under environmental conditions with the controllable process, which uses biodegradable polymer compounds such as pectin and chitosan in its structure. The efficient physicochemical features of the synthesized Cu/DPA-MOF/OP/CS hydrogel using SEM, FT-IR, TGA, BET, XRD, and EDS/mapping were identified and confirmed. The newly synthesized Cu/DPA-MOF/OP/CS hydrogel showed activity against Gram-positive and Gram-negative bacterial strains and fungal species, and significant antibacterial and antifungal properties were observed. In antibacterial activity, the MIC against Gram-positive species was in the range of 16–128 mg/mL, the MIC against Gram-negative species was in the range of 64–256 mg/mL, and the MIC against fungal species was in the range of 128–512 mg/mL. In antimicrobial evaluations, in addition to the MIC test, the MBC test, the MFC test, and the IZD test were performed, and the results were reported. The results were compared with commercial antibiotics in the market. Development of novel nanostructures based on hydrogel polymers with distinctive functionality can affect the performance of these nanostructures in different areas.

Oral ulcers affect oral and systemic health and have high prevalence in the population. There are significant individual differences in the etiology and extent of the disease among patients. In the treatment of oral ulcers, nanofiber films can control the drug-release rate and enable long-term local administration. Compared to other drug-delivery methods, nanofiber films avoid the disadvantages of frequent administration and certain side effects. Electrospinning is a simple and effective method for preparing nanofiber films. Currently, electrospinning technology has made significant breakthroughs in energy-saving and large-scale production. This paper summarizes the polymers that enable oral mucosal adhesion and the active pharmaceutical ingredients used for oral ulcers. Moreover, the therapeutic effects of currently available electrospun nanofiber films on oral ulcers in animal experiments and clinical trials are investigated. In addition, solvent casting and cross-linking methods can be used in conjunction with electrospinning techniques. Based on the literature, more administration systems with different polymers and loading components can be inspired. These administration systems are expected to have synergistic effects and achieve better therapeutic effects. This not only provides new possibilities for drug-loaded nanofibers but also brings new hope for the treatment of oral ulcers.

“…Another is a preparation of complicated structures such as core-shell, Janus, tri-layer core-shell, and 3-section Janus and their combinations from the multiple-fluid processes. The third is the combination of electrospinning with other traditional and advanced chemical methods, such as crosslinking and chemical synthesis, and physical methods, such as 3-D printing (Teixeira et al, 2012;Zhang et al, 2017;Gholami et al, 2020;Kang et al, 2020;Wang et al, 2020;Adamu et al, 2021;Jasim et al, 2022;Liu et al, 2022;Zhao et al, 2022;Zhou et al, 2022;Ge et al, 2023;Liu et al, 2023;Wang et al, 2023;Yu et al, 2023). By using MOF compounds and polyvinyl alcohol with electrospinning methods, various compounds with different applications can be synthesized.…”

Several biological properties of metal–organic frameworks (MOFs) and fiber compounds have been reported, and combinations of these structures can have unique properties. In this study, copper-containing and cobalt-containing MOF nanostructures were synthesized by the ultrasonic technique. Then, novel Cu/Co-hybrid MOF nanostructures were synthesized using the ultrasonic method. Synthesized Cu/Co-hybrid MOF nanostructures were used as a new and efficient recyclable catalyst in the synthesis of pyrano[2,3-c]pyrazole derivatives using the four-component reaction of phenylhydrazine, ethyl acetoacetate, malononitrile, and aldehyde. In the following, novel Cu/Co-hybrid MOF/PVA (poly vinyl alcohol) fiber nanostructures were synthesized by electrospinning and using Cu/Co-hybrid MOF nanostructures and PVA. The structures of the Cu/Co-hybrid MOF nanostructures and the Cu/Co-hybrid MOF/PVA fiber nanostructures were identified and confirmed using BET, TGA, FTIR, SEM, and XRD. In biological studies, the antibacterial, antifungal, and cytotoxicity activities of Cu/Co-hybrid MOF and Cu/Co-hybrid MOF/PVA fiber nanostructures were evaluated. In investigating the catalytic activity of Cu/Co-hybrid MOF, pyrano[2,3-c]pyrazole derivatives were synthesized with higher efficiency and less time than previously reported methods. High antibacterial (against gram-negative and gram-positive strains) and antifungal properties of synthesized Cu/Co-hybrid MOF nanostructures and Cu/Co-hybrid MOF/PVA fiber nanostructures were observed (MIC between 16 and 256 μg/mL), which were higher than some commercial drugs. In the investigation of cytotoxicity activity, the effectiveness on breast cancer cells was studied. The maximum cell proliferation and viability for Cu/Co-hybrid MOF and Cu/Co-hybrid MOF/PVA fiber nanostructures were 38% and 38% higher than the control in a concentration of 200 μg/mL after 48 h. The high catalytic and biological properties of the synthesized nanoparticles can be attributed to the presence of nano-sized bioactive metals and their high specific surface area. The significant physical-chemical properties obtained for synthesized nanoparticles in this study can be related to the desirable synthesis methods, the development of materials with high purity, and the incorporation of hybrid compounds into the nanostructures.
