Contrast-enhanced CT imaging using hafnium oxide nanocrystals

Computed tomography (CT) has revolutionized the way materials are visualized by revealing intricate internal structures which are invisible to the naked eye. However, for many materials their internal structure is virtually unattainable die to the poor CT contrast between different components. The intrinsic material properties of hafnium oxide nanocrystals make them excellent candidates for CT contrast agents. We explore their potential in contrast-enhanced polymer nanocomposites by optimizing their synthesis and surface chemistry, using them in applications such as vascular casting and fiber reinforced polymers.
