<p>The present invention provides a matrix comprising an array of nanostructures that exhibit a variation (gradient) in physical properties (such as size or pitch) in at least one direction of the plane containing said array. A method for forming an array having a gradient property is also provided. In addition, a separation method is provided comprising the steps of: providing a matrix comprising an array of nanostructures arranged so that the array has the property of a gradient; and conducting at least one biomolecule separation process to separate biomolecules in a composition containing a plurality of biomolecules using the matrix.</p> |
