Claim 14:
15. A system for stretching a polynucleotide structure, the system comprising:
a nanochannel having an inlet, an outlet, a first end region, and a second end region, the inlet of the nanochannel is tapered;
a first electrode positioned adjacent to the first end region of the nanochannel, the first electrode being positively charged;
a second electrode positioned adjacent to the second end region of the nanochannel, the second electrode being negatively charged, the first and second electrodes being configured to generate an electric force along an axial direction of the nanochannel to guide the polynucleotide structure into the nanochannel to stretch the polynucleotide structure along the axial direction of the nanochannel; and
a third electrode positioned adjacent to the inlet of the nanochannel and configured to generate an electrostatic force perpendicular to a surface of the third electrode and to apply the electrostatic force to the polynucleotide structure to pin an end region of the polynucleotide structure near the surface of the third electrode.
