Implantable intracortical microelectrodes face an uphill struggle for widespread clinical use. Their potential for treating a wide range of traumatic and degenerative neural disease is hampered by their unreliability in chronic settings. A major factor in this decline in chronic performance is a reactive response of brain tissue, which aims to isolate the implanted device from the rest of the healthy tissue. In this review we present a discussion of materials approaches aimed at modulating the reactive tissue response through mechanical and biochemical means. Benefits and challenges associated with these approaches are analyzed, and the importance of multimodal solutions tested in emerging animal models are presented.
可植入式皮层内微电极在广泛临床应用上面临着艰巨的挑战。它们在治疗多种创伤性和退行性神经疾病方面的潜力因在慢性环境中的不可靠性而受到阻碍。慢性性能下降的一个主要因素是脑组织的反应性反应,其目的是将植入装置与其余健康组织隔离开来。在这篇综述中,我们讨论了旨在通过机械和生化手段调节反应性组织反应的材料方法。分析了与这些方法相关的益处和挑战,并介绍了在新兴动物模型中测试的多模式解决方案的重要性。
