中枢神经系统(CNS)疾病是未满足医疗需求的最大和增长最快的领域。纳米技术在脑特异性药物输送、成像和诊断的革命性发展中发挥着独特的工具性作用。借助树状大分子和量子点等具有高特异性和多功能性的纳米颗粒,治疗药物、显像剂和诊断分子可以通过血脑屏障(BBB)输送到大脑,从而在理解、诊断和治疗中枢神经系统疾病方面取得重大进展。本文综述了用于中枢神经系统药物传递、成像和诊断的纳米颗粒,以及它们的给药途径、毒性和穿过血脑屏障的途径。概述了未来的发展方向和主要挑战。
Central nervous system (CNS) diseases represent the largest and fastest growing area of unmet medical need. Nanotechnology plays a unique instrumental role in the revolutionary development of brain-specific drug delivery, imaging, and diagnosis. With the aid of nanoparticles of high specificity and multifunctionality, such as dendrimers and quantum dots, therapeutics, imaging agents, and diagnostic molecules can be delivered to the brain across the blood-brain barrier (BBB), enabling considerable progress in the understanding, diagnosis, and treatment of CNS diseases. Nanoparticles used in the CNS for drug delivery, imaging, and diagnosis are reviewed, as well as their administration routes, toxicity, and routes to cross the BBB. Future directions and major challenges are outlined.
