Heparin‐Coated Gold Nanoparticles for Liver‐Specific CT Imaging

Gold nanoprobe: Heparin–DOPA-coated gold nanoparticles (HEPA–AuNPs) showed low toxicity, prolonged stability, and an enhanced X-ray absorption coefficient in vitro. In vivo microCT images showed that HEPA–AuNPs produced enhanced liver-specific CT images compared with iodine-based contrast agents, thus highlighting its potential as a novel, liver-specific CT imaging agent (see figure).
