Nano-assembled capsules can incorporate large payloads of high relaxivity Gd, permitting the development of highly detectable molecular imaging agents for MRI. A new encapsulating shell, based upon cross-linked peptides, is found to afford smaller capsules (127 nm average diameter) with exceptionally high per-Gd relaxivities (70.7 s mmolal).
纳米组装胶囊可以容纳大量具有高弛豫率的钆,从而开发出用于磁共振成像(MRI)的高可检测性分子成像剂。人们发现一种基于交联肽的新型封装壳能够提供更小的胶囊(平均直径127纳米),其每钆弛豫率极高(70.7 s/mmol)。
