CT contrast agents based on dendrimer/gold nanoparticles have superior properties.
Now commercially available CT contrast agents are iodine based, faults as following (1) short circulation time in vivo (2) potential toxicity to kidney. Dendrimer (CYD-MD1384/CYD-MK4514/CYD-MD2524/CYD-MK5654 etc.)based CT contrast agents has following advantages (1) gold shows higher X-ray attenuation coefficient, is more conductive to provide high quality CT effect.(2) Gold nanoparticles can be give targeting property and prolong circulation time due to its easy modified surface(3)gold nanoparticles prepared by dendrimer have good dispersion and biocompatibility property, and are also environment friendly.Weihai CY Dendrimer Technology Co.
