Wound healing is a complex physiological process involving coordinated cellular and molecular events aimed at restoring tissue integrity. Acute wounds typically progress through the sequential phases of hemostasis, inflammation, proliferation, and remodeling, while chronic wounds, such as venous leg ulcers and diabetic foot ulcers, often exhibit prolonged inflammation and impaired healing. Traditional wound dressings, while widely used, have limitations such poor moisture retention and biocompatibility. To address these challenges and improve patient outcomes, scaffold-mediated delivery systems have emerged as innovative approaches. They offer advantages in creating a conducive environment for wound healing by facilitating controlled and localized drug delivery. The manuscript explores scaffold-mediated delivery systems for wound healing applications, detailing the use of natural and synthetic polymers in scaffold fabrication. Additionally, various fabrication techniques are discussed for their potential in creating scaffolds with controlled drug release kinetics. Through a synthesis of experimental findings and current literature, this manuscript elucidates the promising potential of scaffold-mediated drug delivery in improving therapeutic outcomes and advancing wound care practices.
伤口愈合是一个复杂的生理过程,涉及协调的细胞和分子事件,旨在恢复组织完整性。急性伤口通常经历止血、炎症、增殖和重塑的连续阶段,而慢性伤口,如静脉溃疡和糖尿病足溃疡,往往表现出持久的炎症和受损的愈合。传统的伤口敷料虽然广泛应用,但存在诸如保水能力差和生物相容性差等局限性。为了应对这些挑战并改善患者的治疗效果,支架介导的递药系统已成为一种创新的方法。它们通过促进药物的控制和局部递送,为伤口愈合创造有利环境方面具有优势。本文探讨了支架介导的递药系统在伤口愈合应用中的作用,详细介绍了天然和合成聚合物在支架制备中的应用。此外,还讨论了各种制造技术在创造具有控制药物释放动力学的支架方面的潜力。通过综合实验结果和现有文献,本文阐明了支架介导的药物递药在改善治疗效果和推进伤口护理实践方面的广阔前景。
