<P>PROBLEM TO BE SOLVED: To provide an apparatus, a system and a method for controlling a polymer through a nanopore using a piezoelectric material. <P>SOLUTION: There are provided an apparatus, a system, and a method for using a piezoelectric material for controlling a polymer through a nanopore. A reservoir is formed filled with a conductive fluid. A nanopore is formed through a membrane. The membrane comprises an electroconductive layer, a piezoelectric layer, and an insulating layer. The piezoelectric layer is operative to control a size of the nanopore for clamping/releasing a polymer as well as to control the thickness of part of the membrane when a voltage is applied to the piezoelectric layer. Combinations of clamping/releasing the polymer and changing the thickness of part of the membrane can move a polymer through the nanopore at any electrically controlled speed and also stretch or break a polymer in the nanopore. <P>COPYRIGHT: (C)2011,JPO&INPIT |
