The aim of this work was to synthesize, characterize and apply advanced antimicrobial biocompatible electrospun polymers suitable for medical implants for surgical repairs. Injuries to the musculoskeletal system often necessitate surgical repair, but current treatments can still lead to high failure rates, such as 40% for the repair of rotator cuff tears. Therefore, there is an urgent need for the development of new biocompatible materials that can effectively support the repair of damaged tissues. Additionally, infections acquired during hospitalization, particularly those caused by antibiotic-resistant bacteria, result in more fatalities than AIDS, tuberculosis, and viral hepatitis combined. This underscores the critical necessity for the advancement of antimicrobial implants with specialized coatings capable of combating () and (), two strains notoriously known for their antibiotic resistance. Therefore, we developed an antimicrobial coating incorporating nanoparticle mixtures using the sol-gel process and applied it to electrospun polycaprolactone (PCL) filaments, followed by thorough characterization by using spectroscopic (FTIR, Raman, NMR) microscopic (SEM and SEM-EDX), and tensile test. The results have shown that the integration of electro-spinning technology for yarn production, coupled with surface modification techniques, holds significant potential for creating antimicrobial materials suitable for medical implants for surgical repairs.
这项工作的目的是合成、表征并应用适用于外科修复医疗植入物的先进抗菌生物相容性电纺聚合物。肌肉骨骼系统损伤常常需要进行手术修复,但目前的治疗方法仍可能导致较高的失败率,比如肩袖撕裂修复的失败率为40%。因此,迫切需要开发能够有效支持受损组织修复的新型生物相容性材料。此外,住院期间获得的感染,尤其是由耐抗生素细菌引起的感染,导致的死亡人数超过了艾滋病、结核病和病毒性肝炎的总和。这凸显了开发具有特殊涂层的抗菌植入物的紧迫性,这种涂层能够对抗()和()这两种以抗生素耐药性而臭名昭著的菌株。因此,我们利用溶胶 - 凝胶工艺开发了一种包含纳米颗粒混合物的抗菌涂层,并将其应用于电纺聚己内酯(PCL)长丝,随后通过光谱(FTIR、拉曼、NMR)、显微镜(SEM和SEM - EDX)以及拉伸试验进行全面表征。结果表明,将用于纱线生产的电纺技术与表面改性技术相结合,在制造适用于外科修复医疗植入物的抗菌材料方面具有巨大潜力。
