description Functionalized poly(amido amine) (PAMAM) dendrimer nanostructures with redox activity and catalytic ability were for the first time utilized as detectable signal tags for highly efficiency electrochemical immunosensing of low-abundance protein (prostate-specific antigen, PSA, used as a model) on a disposable immunosensor, based on an in situ amplification strategy of bioelectrocatalytic reaction.
