Abstract

We synthesized dendrimer composite nanoparticles and investigated their potential for traditional X-ray imaging and Computed Tomography (CT). These new X-ray contrast agents show better contrast compared to traditional iodine-based contrast agents, and are expected to clear from the blood much slower than commercial agents, permitting longer imaging times. We have also investigated their safety profile in terms of viscosity and osmotic pressure.
