Dysregulation of sequential and synchronized events of skin regeneration often results in the impairment of chronic wounds. Conventional wound dressings fail to trigger the normal healing mechanism owing to the pathophysiological conditions. Tissue engineering approaches that deal with the fabrication of dressings using various biomaterials, growth factors, and stem cells have shown accelerated healing outcomes. However, most of these technologies are associated with difficulties in scalability and cost-effectiveness of the products. In this review, we survey the latest developments in wound healing strategies that have recently emerged through the multidisciplinary approaches of bioengineering, nanotechnology, 3D bioprinting, and similar cutting-edge technologies to overcome the limitations of conventional therapies. We also focus on the potential of wearable technology that supports complete monitoring of the changes occurring in the wound microenvironment. In addition, we review the role of advanced devices that can precisely enable the delivery of nanotherapeutics, oligonucleotides, and external stimuli in a controlled manner. These technological advancements offer the opportunity to actively influence the regeneration process to benefit the treatment regime further. Finally, the clinical relevance, trajectory, and prospects of this field have been discussed in brief that highlights their potential in providing a beneficial wound care solution at an affordable cost.
皮肤再生过程中顺序和同步事件的失调常常导致慢性伤口受损。由于病理生理条件的限制,传统的伤口敷料无法触发正常的愈合机制。采用各种生物材料、生长因子和干细胞制造敷料的组织工程方法已经显示出加速愈合的效果。然而,这些技术大多存在产品规模化和成本效益方面的困难。在这篇综述中,我们通过生物工程、纳米技术、3D 生物打印和类似的前沿技术的多学科方法,调查了最近在伤口愈合策略方面的最新进展,以克服传统疗法的局限性。我们还重点介绍了可穿戴技术的潜力,该技术可以支持对伤口微环境中发生的变化进行全面监测。此外,我们还回顾了先进设备在以可控方式精确输送纳米药物、寡核苷酸和外部刺激物方面的作用。这些技术进步为积极影响再生过程提供了机会,从而进一步有益于治疗方案。最后,简要讨论了该领域的临床相关性、轨迹和前景,突出了它们在以可承受的成本提供有益的伤口护理解决方案方面的潜力。
