Global concern about Alzheimer's disease (AD) is justified by its increasingly younger onset and significant economic burden. AD leads to neurodegeneration and cognitive decline, ultimately resulting in loss of autonomy. Against this background, the field of biomedical research has seen a surge of interest in the potential of carbon-based nanomaterials, mainly due to their ease of degradation and high biocompatibility. Carbon nanotubes (CNTs) have been extensively studied in AD, including developing biosensors, drug delivery systems, and molecular imaging. Here, we introduced the biosafety and biodegradability of CNTs, with a particular focus on their uptake and degradation in brain tissue. The utilization of CNT in the context of AD therapy can facilitate the advancement of control approaches regimens and ensure the clinical safety of patients. This is achieved through the employment of these nanotubes as carriers for the delivery of drugs to the central nervous system (CNS), the detection of neurotransmitters such as acetylcholine (Ach) and monoamines, the development of biosensors and molecular imaging materials, the inhibition of Aβ formation and the detection of phosphorylated tau proteins, the promotion of CNS regeneration, and the modulation of ion-associated AD.
全球对阿尔茨海默病(AD)的关注是合理的,因为其发病年龄越来越年轻化,且经济负担沉重。AD会导致神经退行性变和认知能力下降,最终导致自主能力丧失。在此背景下,生物医学研究领域对碳基纳米材料的潜力产生了浓厚兴趣,主要是因为它们易于降解且生物相容性高。碳纳米管(CNTs)已在AD研究中得到广泛应用,包括开发生物传感器、药物递送系统和分子成像技术。在此,我们介绍了碳纳米管的生物安全性和生物降解性,特别关注它们在脑组织中的摄取和降解情况。在AD治疗中利用碳纳米管有助于推进控制方案,并确保患者的临床安全。这是通过将这些纳米管用作药物递送至中枢神经系统(CNS)的载体、检测神经递质如乙酰胆碱(Ach)和单胺类、开发生物传感器和分子成像材料、抑制Aβ形成和检测磷酸化tau蛋白、促进CNS再生以及调节与离子相关的AD来实现的。
