Patent ID: 8641879

Claim:
A method for controlling one or more charged entities linked to a polymer through a nanochannel, the method comprising: connecting a first reservoir and a second reservoir by the nanochannel, an array of electrodes being positioned along the nanochannel, wherein fluid fills the first reservoir, the second reservoir, and the nanochannel; and configuring a first electrode in the first reservoir and a second electrode in the second reservoir, the first and second electrodes being configured to direct the one or more charged entities linked to the polymer into the nanochannel; wherein the array of electrodes is configured to trap the one or more charged entities in the nanochannel responsive to being controlled for trapping; wherein a voltage bias having a polarity scheme is applied via the voltage source to a triplet electrode group, all at one time, in the array of electrodes to trap a single charged entity attached to the one or more charged entities along the nanochannel in which the triplet electrode group is simultaneously aligned to and corresponds to the single charged entity; wherein the polarity scheme to trap the single charged entity includes positive and negative voltage biases applied to the triplet electrode group according to a charge of the single charged entity; and wherein the array of electrodes is configured to move the one or more charged entities along the nanochannel responsive to being controlled for moving.
