X-ray contrast agent using gold nanoparticles and process for preparing the same

摘要

The present invention relates to an X- ray contrast agent and a method using a gold nanoparticle , the present invention X- ray contrast agent is combined with polyethylene glycol (PEG) to the gold nanoparticles developed by the toxicity is not available and special intravascular residence time is increased to be useful as a CT (Computed Tomography) contrast agent for imaging blood vessels . ; Therefore, it is useful to observe angiogenesis in vivo vascular structure and its changes and tumor tissue , even to get a perfusion (perfusion) images of the tumor tissue is useful . ; in addition , of gold and has an X- ray imaging is highly effective properties than iodine , it is possible to obtain a better image when using the concentration of the contrast agent , such as existing .
