Abstract
The challenge of healing burn wounds is significant importance in global healthcare systems, with a high demand for advanced wound dressings to aid in the treatment of such injuries. Promising options include bioactive electrospun scaffolds made from polymers with antimicrobial properties, which can prevent infections and promote faster healing. This study involved the creation of a nanofibrous scaffold using the electrospinning technique, which consisted of polyvinyl alcohol (PVA), alginate (Alg), and Dragon's blood (DB). The scaffold was then analyzed for both its morphology and chemical composition. Results indicated that the DB was present in the nanofibrous scaffold, which had a uniform and unbranched appearance with fibers measuring approximately 300–400 nm in diameter. Additionally, mechanical property testing revealed promising results that fall within the range of human skin. The scaffold's wound healing potential was evaluated through various measurements, including water contact angle, drug release, water vapor permeability, blood compatibility, blood clotting index, and antibacterial activity. Results from an in vivo study on burn wounds showed that scaffolds containing 20% DB exhibited excellent wound healing ability with 80.3% wound closure after 21 days. This was attributed to the highest collagen synthesis, re-epithelization and remodeling of the burned skin. Therefore, PVA/Alg/DB nanofibrous scaffolds hold promise as a wound dressing to treat burn injuries.
期刊介绍：
Journal of Biomedical Materials Research – Part B: Applied Biomaterials is a highly interdisciplinary peer-reviewed journal serving the needs of biomaterials professionals who design, develop, produce and apply biomaterials and medical devices. It has the common focus of biomaterials applied to the human body and covers all disciplines where medical devices are used. Papers are published on biomaterials related to medical device development and manufacture, degradation in the body, nano- and biomimetic- biomaterials interactions, mechanics of biomaterials, implant retrieval and analysis, tissue-biomaterial surface interactions, wound healing, infection, drug delivery, standards and regulation of devices, animal and pre-clinical studies of biomaterials and medical devices, and tissue-biopolymer-material combination products. Manuscripts are published in one of six formats:
• original research reports
• short research and development reports
• scientific reviews
• current concepts articles
• special reports
• editorials
Journal of Biomedical Materials Research – Part B: Applied Biomaterials is an official journal of the Society for Biomaterials, Japanese Society for Biomaterials, the Australasian Society for Biomaterials, and the Korean Society for Biomaterials. Manuscripts from all countries are invited but must be in English. Authors are not required to be members of the affiliated Societies, but members of these societies are encouraged to submit their work to the journal for consideration.
