    摘要: A solid state nanopore device including two or more materials and a method for fabricating the same. The device includes a solid state insulating membrane having an exposed surface, a conductive material disposed on at least a portion of the exposed surface of the solid state membrane, and a nanopore penetrating an area of the conductive material and at least a portion of the solid state membrane. During fabrication a conductive material is applied on a portion of a solid state membrane surface, and a nanopore of a first diameter is formed. When the surface is exposed to an ion beam, material from the membrane and conductive material flows to reduce the diameter of the nanopore. A method for evaluating a polymer molecule using the solid state nanopore device is also described. The device is contacted with the polymer molecule and the molecule is passed through the nanopore, allowing each monomer of the polymer molecule to be monitored.
