Abstract
A mechanism is provided for manipulating a molecule. The molecule is driven into a nanochannel filed with electrically conductive fluid. A first vertical electric field is created inside the nanochannel to slow down the molecule and/or immobilize the molecule. The molecule is stretched into non-folded linear chains by the first vertical electric field and a horizontal electric field. Monomers of the molecule are sequentially read.
Claims14
A method for manipulating a molecule, the method comprising:
- driving the molecule into a nanochannel filed with electrically conductive fluid;
- creating a first vertical electric field inside the nanochannel to at least one of:
- slow down the molecule and immobilize the molecule;
- stretching the molecule into non-folded linear chains by the first vertical electric field and a horizontal electric field;
- and
- sequentially reading monomers of the molecule.
