摘      要：Gold nanoparticles functionalized hollow mesoporous Prussian blue nanoparticles(Au@HMPB NPs)were synthesized and its peroxidase-like activity was explored for electrochemical *** Au@HMPB NPs can reduce H2O2 low detection potential of-0.1 V with high *** physically adsorption of antibodies onto the gold nanoparticle surface,the functionalized nanoparticles were turned into *** soluble a-chain of interleukin-2(IL-2)receptor(sCD25)was chosen as a model protein biomarker to test the performance of the ***25 in the samples were captured and enriched by capture anti-CD25 antibody functionalized magnetic *** antibody functionalized Au@HMPB can then be linked onto the nanospheres and generate electrochemical current towards H2O2 *** electrochemical responses to 1 mmol/L H2O2 was increased with the increasing concentration of CD25.
