Label-free electrochemiluminescence detection of specific-sequence DNA based on DNA probes capped ion nanochannels

As one of the powerful molecular recognition elements, the functional DNA probes have been successfully utilized to construct various biosensors. However, the accurate readout of the recognition event of DNA probe binding to the specific target by label-free means is still challenging. Here, a simpl...
