摘要
Provided are an X-ray contrast agent using gold nanoparticles and a process for preparing the X-ray contrast agent. The X-ray contrast agent is prepared by capping gold nanoparticles with polyethylene glycol (PEG). The X-ray contrast agent is nontoxic and remains in a blood vessel for a long time so that the X-ray contrast agent can be usefully used as a computed tomography (CT) contrast agent for imaging blood vessels. Therefore, the X-ray contrast agent is useful for inspecting blood vessel structures and new blood vessels in a tumor, and obtaining perfusion images. In addition, gold provides better visibility than iodine when used in an X-ray contrast agent. Therefore, better x-ray images can be obtained using the X-ray contrast agent containing gold nanoparticles.
