Claim:
1. A device for voltage sensing of analytes, the device comprising: a plurality of fluidic channels, each defined by a trench in a substrate, each fluidic channel having at least one pair of sensing electrodes defining a detection zone disposed in each of the channels for sensing voltage therein, each detection zone comprising a first and a second sensing electrode disposed at two discrete laterally offset locations along a length of each fluidic channel, the sensing electrodes being connected to a voltmeter for measuring a voltage sensed by the sensing electrodes, and the pair of sensing electrodes not being connected to a voltage source; a first common channel disposed at the first ends of the plurality of fluidic channels; a second common channel disposed at the second ends of the plurality of fluidic channels; and at least one electromotive electrode disposed in each of the first and second common channels for applying a potential along the fluidic channels, wherein the fluidic channels each comprise a nanochannel or a microchannel.
