A signal amplification strategy was proposed for quantum dot-based electrochemiluminescence by an adsorption-induced catalytic reduction of dissolved oxygen at the sidewall of nitrogen-doped carbon nanotubes, which led to a 'signal-on' sandwich immunoassay with a linear range of 6 orders of magnitude. |
