Schematic representation of the fabrication of the electrochemical enzyme-linked immunoassay for the detection of cell-surface glycans. Human epithelial carcinoma cells were captured on a glassy carbon electrode modified with nitrogen-doped carbon nanotubes, gold nanoparticles, and Con A. The enzyme HRP was incorporated to the electrode by two-step immunoreactions, and its catalytic reaction towards the oxidation of thionine by H2O2 was monitored. Reprinted with permission from [54].
