Abstract
Pathways to rapid and reliable fabrication of nanocylinder arrays are provided. Simple methods are described for the production of well-ordered arrays of nanopores, nanowires, and other materials. This is accomplished by orienting copolymer films and removing a component from the film to produce nanopores, that in turn, can be filled with materials to produce the arrays. The resulting arrays can be used to produce nanoscale media, devices, and systems.
Claims53
A method of preparing an array of nanopores, the method comprising:
- at least partially coating a conducting or semiconducting substrate with a copolymer comprising a first component and a second component;
- mobilizing molecules in the copolymer for a time sufficient to allow the first component of the copolymer to form nanoscopic cylinders within the second component of the copolymer;
- orienting the nanoscopic cylinders of the first component within the second component to form an oriented copolymer;
- immobilizing molecules in the oriented copolymer;
- and
- removing at least a portion of the first component from the oriented copolymer to form an array of nanopores in the copolymer.
A nanopore array comprising a polymer matrix and a plurality of nanopores within the matrix, the nanopores each having a diameter of from 1.0 to 100 nanometers and a having a periodicity of from 1.0 to 100 nanometers.
A nanoscale array comprising a substrate and nanowires arranged in parallel on the substrate, the nanowires each having a diameter of 1.0 to 100 nanometers, and having a periodicity of 1.0 to 100 nanometers.
A magnetic array comprising a substrate and an array of nanoscopic cylinders comprising a magnetic material and arranged in parallel on the substrate.
