A spray-on wound dressing has many benefits, including easy and quick administration to broad and uneven wounds, better interface with the wound site, adhesion without additional dressing, and multiple applications in a portable package. By limiting direct contact with the wound site, such a design can prevent wound damage during treatment. This study revealed a simple, one-pot synthesis of spray-on wound dressing relying on polyvinylpyrrolidone solution incorporating silver nanoparticles as a broad-spectrum antibacterial agent and wound-healing antioxidant extract. Silver nanoparticles were synthesized in situ using extract as a biogenic reducing agent. Polyvinylpyrrolidone was employed as a film-forming agent to create an adhesive hydrogel-based dressing matrix to provide moisture and establish a shielding barrier for the wound bed as well as to regulate the release of fruit extract. In vitro tests revealed that the produced dressing film had a controlled release of the fruit extract, high antioxidant activity, and a good antibacterial action against , , , and MRSA. Additionally, a biocompatibility study has shown that both human fibroblasts and keratinocytes are unaffected by the dressing film. Based on established findings, the current spray-on solution might be a potential option for antibacterial wound dressing.
一种喷雾式伤口敷料有许多优点,包括易于快速应用于大面积和不平整的伤口、与伤口部位的贴合性更好、无需额外敷料即可粘附,以及可在便携式包装中多次使用。通过限制与伤口部位的直接接触,这种设计可以防止治疗过程中对伤口造成损伤。本研究揭示了一种简单的一锅法合成喷雾式伤口敷料的方法,该方法依赖于含有银纳米颗粒的聚乙烯吡咯烷酮溶液,银纳米颗粒作为广谱抗菌剂和促进伤口愈合的抗氧化提取物。使用提取物作为生物还原剂原位合成银纳米颗粒。聚乙烯吡咯烷酮用作成膜剂,以创建基于粘合剂水凝胶的敷料基质,提供水分并为伤口床建立屏蔽屏障,以及调节水果提取物的释放。体外测试表明,所制备的敷料膜对水果提取物具有可控释放、高抗氧化活性,并且对大肠杆菌、金黄色葡萄球菌、铜绿假单胞菌和耐甲氧西林金黄色葡萄球菌具有良好的抗菌作用。此外,一项生物相容性研究表明,人成纤维细胞和角质形成细胞均不受敷料膜的影响。基于已有的研究结果,目前这种喷雾式溶液可能是抗菌伤口敷料的一个潜在选择。
