我们报道了水合Gd3+(N)离子在超短单壁碳纳米管(US管)中的纳米级负载和限制；这些Gd3+(N)@US管物种是线性超顺磁性分子磁体，其磁共振成像(MRI)效率是目前临床使用的任何基于Gd3+的造影剂(CA)的40到90倍。
We report the nanoscale loading and confinement of aquated Gd3+ (n)-ion clusters within ultra-short single-walled carbon nanotubes (US-tubes); these Gd3+ (n)@US-tube species are linear superparamagnetic molecular magnets with Magnetic Resonance Imaging (MRI) efficacies 40 to 90 times larger than any Gd3+-based contrast agent (CA) in current clinical use.
