Abstract

Au nanoparticles-loaded metal organic framework compounds with ultranano-structured（ Au/SNHKUST-1） is synthesized at room temperature and use it as a tag to label anti C-creative protein（ CRP）. Hollow graphene nanomaterials and Au nanoparticles are also synthesized and utilized as immobilized matrix. The quantitative determination of CRP can be achieved by detecting the catalytic current of label to the reduction of H

. The response current has a good linear relationship with CRP concentration at range of 0.2

200 ng/m L with linear correlation coefficient of 0.9947 and the lowest detection limit is 0.05 ng/m L. This immunosensor of CRP provides a new simple and rapid detection me

thod for CRP.
