Classification: CPC B  C  G | IPC A  B  C  G

Claim 8:
9. The multi-stage system of claim 8, further comprising:
a third nanochannel having a third inlet and a third outlet, the third nanochannel being positioned adjacent to the second outlet of the second nanochannel; and
a fifth electrode positioned adjacent to the third inlet of the third nanochannel and between the second and the third nanochannel, the fifth electrode being configured to sense a presence of the first end region of the polynucleotide structure when a portion of the polynucleotide structure extends beyond the second outlet of the second nanochannel and to generate a third electrostatic force perpendicular to a surface of the fifth electrode, the fifth electrode being activated upon sensing the presence of the first end region of the polynucleotide structure and the third electrode being deactivated to release the second end region of the polynucleotide structure, the fifth electrode being configured to apply the third electrostatic force to the polynucleotide structure to pin the first end region of the polynucleotide structure near the surface of the fifth electrode, the first and second electrodes being configured to generate a third electric force to guide the polynucleotide structure through the third nanochannel.
