Melanoma cancer wound healing is critical and complex and poses a significant challenge to researchers. Drug resistance, adverse side effects, and inefficient localization of chemotherapeutic drugs limit common treatment strategies in melanoma cancer. Using drug delivery nanostructures with low side effects and high efficiency, besides having antibacterial and antiseptic properties, can effectively repair the damage caused by the disease. To this end, this study aimed to develop a drug delivery nanosystem based on doxorubicin (DOX)-loaded amine-functionalized mesoporous silica nanoparticles (MSNs), linked with green synthesized silver nanoparticles (AgNPs). Characterization methods including microscopic methods and X-ray diffraction (XRD) confirmed the synthesis and functionalization of the well-dispersed nanoparticles with nanosized and uniform structures. The poly(ε-caprolactone) (PCL) nanofibers as a strong scaffold were produced by the blow spinning method and DOX-loaded nanoparticles were blow spun on PCL nanofibers along with gelatin solution. The resulting nanosystem including nanofibers and nanoparticles (NFs/NPS) showed a fine loading percent with a proper release profile of DOX and AgNPs and low hemolysis activity. Moreover, besides preventing infection by AgNPs, the DOX-loaded NFs/NPs could effectively destroy melanoma cancer cells. The attachment of normal cells to the nanoparticles-loaded nanofibers scaffold revealed the possibility of healing wounds caused by melanoma cancer.
黑色素瘤癌症伤口愈合至关重要且复杂,给研究人员带来了重大挑战。耐药性、不良副作用以及化疗药物定位效率低下限制了黑色素瘤癌症的常见治疗策略。使用具有低副作用和高效率的药物递送纳米结构,除了具有抗菌和防腐性能外,还能有效修复疾病造成的损伤。为此,本研究旨在开发一种基于负载阿霉素(DOX)的胺功能化介孔二氧化硅纳米颗粒(MSN)与绿色合成的银纳米颗粒(AgNP)相连的药物递送纳米系统。包括显微镜方法和X射线衍射(XRD)在内的表征方法证实了具有纳米尺寸且结构均匀的分散良好的纳米颗粒的合成与功能化。通过吹纺法制备了作为强支架的聚(ε-己内酯)(PCL)纳米纤维,并将负载DOX的纳米颗粒与明胶溶液一起吹纺到PCL纳米纤维上。所得的包括纳米纤维和纳米颗粒(NFs/NPS)的纳米系统显示出良好的负载率,DOX和AgNP具有适当的释放曲线且溶血活性低。此外,除了通过AgNP预防感染外,负载DOX的NFs/NPs还能有效破坏黑色素瘤癌细胞。正常细胞附着在负载纳米颗粒的纳米纤维支架上表明了治愈黑色素瘤癌症所致伤口的可能性。
