“…25 In addition, N6 has favorable mechanical properties and, unlike many common electrospinnable polymers that dissolve in highly toxic solvents such as dimethylformamide (DMF), dimethylsulfoxide (DMSO), and so forth, dissolves in acetic acid and formic acid, which are less toxic. 26 Because of its nonallergenic nature and biocompatibility, it has been used in various medical fields, such as wound dressings, scaffolds with three-dimensional structures for use in tissue engineering, and drug release systems. 27 Parin and coworkers developed an electrospun N6-honey-boric acid mat with bioactivity, wettability, and wound healing capabilities.…”

Hyaluronic acid (HA) and chitosan (CS), as natural biomaterials, display excellent biocompatibility and stimulate the growth and proliferation of fibroblasts. Furthermore, nylon 6 (N6) is a low‐cost polymer with good compatibility with human tissues and high mechanical stability. In this study, HA and CS were applied to modify N6 nanofibrous mat (N6/HA/CS) for potential wound dressing. N6/HA/CS nanofibrous composite mats were developed using a simple one‐step electrospinning technique at different CS concentrations of 1, 2, and 3 wt%. The results demonstrated that incorporating HA and CS into N6 resulted in increased hydrophilicity, as well as favorable physical and mechanical properties. In addition, the minimum inhibitory concentration and (MIC) optical density techniques were used to determine the antibacterial properties of N6/HA/CS nanofibrous composite mats, and the results demonstrated that the composites could markedly inhibit the growth of Gram‐positive bacteria Staphylococcus aureus and Gram‐negative bacteria Escherichia coli. Because of its superior mechanical properties, substantial antimicrobial effects, and hydrophilic surface, N6/HA/CS at 2 wt% of CS (N6/HA/CS2) was chosen as the most suitable nanofibrous mat. The swelling, porosity, gel content, and in vitro degradation studies imply that N6/HA/CS2 nanofibrous composite mat has proper moisture retention and biodegradability. Furthermore, the N6/HA/CS2 nanofibrous composite mat was discovered to be nontoxic to L929 fibroblast cells and to even improve cell proliferation. Based on the findings, this research offers a simple and rapid method for creating material that could be utilized as prospective wound dressings in clinical environments.

“…[20] Besides great mechanical properties, high tensile strength, and flexibility, PA6 possesses excellent thermal properties and high chemical stability. [21][22][23][24][25][26] Nonetheless, it can be easily electrospun in combination with a wide variety of materials. The desirable mechanical properties of PA6 paved the way for commercialization, and it is currently utilized in a variety of medical devices.…”

Various wound dressings have been developed so far for wound healing, but most of them are ineffective in properly reestablishing the skin's structure, which increases infection risks and dehydration. Electrospun membranes are particularly interesting for wound dressing applications because they mimic the extracellular matrix of healthy skin. In this study, a potential wound healing platform capable of inducing synergistic antibacterial and antioxidation activities was developed by incorporating bio‐active rosmarinic acid‐hydroxyapatite hybrid (HAP‐RA) with different contents (0.5, 1, and 1.5 wt.%) into the electrospun polyamide 6 (PA6) nanofibers. Then, polyethylene glycol (PEG) was introduced to the nanofibrous composite to improve the biocompatibility and biodegradability of the dressing. The results indicated that the hydrophilicity, water uptake, biodegradability, and mechanical properties of the obtained PA6/PEG/HAP‐RA nanofibrous composite enhanced at 1 wt.% of HAP‐RA. The nanofibrous composite had excellent antibacterial activity. The antioxidation potential of the samples was assessed in vitro. The MTT assay performed on the L929 cell line confirmed the positive effects of the nanofibrous scaffold on cell viability and proliferation. According to the results, the PA6/PEG/HAP‐RA nanofibrous composite showed the desirable physiochemical and biological properties besides antibacterial and antioxidative capabilities, making it a promising candidate for further studies in wound healing applications.
