Abstract

Nanoscale metal-organic frameworks (NMOFs) of the UiO-66 structure containing high Zr (37 wt%) and Hf (57 wt%) content were synthesized and characterized, and their potential as contrast agents for X-ray computed tomography (CT) imaging was evaluated. Hf-NMOFs of different sizes were coated with silica and poly(ethylene glycol) (PEG) to enhance biocompatibility, and were used for in vivo CT imaging of mice, showing increased attenuation in the liver and spleen.

作为计算机断层扫描造影剂的锆和铪基纳米级金属有机框架。
合成并表征了高Zr(37 wt%)和Hf(57 wt%)含量的UiO-66结构纳米级金属有机框架(NMOFs),并评估了它们作为X射线计算机断层扫描(CT)成像造影剂的潜力。在不同尺寸的 Hf-NMOFs 上涂覆了二氧化硅和聚乙二醇 (PEG) 以增强其生物相容性,并将其用于小鼠体内 CT 成像,结果显示肝脏和脾脏的衰减增加。
