CONTRAST AGENT BASED ON GRAPHENE OXIDE MATERIAL AND PREPARATION METHOD THEREFOR

摘要

A contrast agent based on graphene oxide material and preparation method therefor. The contrast agent has a structure represented by formula I: A-(B-R)n, wherein A is graphene oxide, R is gadolinium metal complex, B is bridging molecule, and A, B and R are bonded to each other via chemical bond. The contrast agent has characteristics of high relaxation, good stability, non-specificity and the like.
