摘要
一类被注射到患者体内以便疾病能够被诊断的复合材料已经在纳米级别上成为位点特异性药物输送系统的根基。被多聚体包埋以便其在血流中分散的铁氧颗粒胶囊通常被用于磁共振成像技术。现在研究者正在把经包埋的磁性晶体的原理改用到一系列活性比率高且对正常组织影响低的药物治疗中。
Aclass of composite materials that is injected into patients to enable the diagnosis of disease has, on the nano-scale, emerged as the basis of site-specific drug delivery systems. Iron oxide particles encapsulated in polymers to enable them to disperse in the bloodstream are commonly used in magnetic resonance imaging techniques. Now researchers are adapting the principle of coated magnetic nanocrystals to a range of drug therapies combining high rates of activity with low impact on normal tissue.
