Nanoelectrode ensembles as recognition platform for electrochemical immunosensors [PDF]

Biosensors and Bioelectronics, 2008
In this study we demonstrate the possibility to prepare highly sensitive nanostructured electrochemical immunosensors by immobilizing biorecognition elements on nanoelectrode ensembles (NEEs) prepared in track-etch polycarbonate membranes. The gold nanodisk electrodes act as electrochemical transducers while the surrounding polycarbonate binds the ...
