Patent number 8617412 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "In separation technology, separation and identification of small molecules from larger ones is often performed. Separation may be employed, for example, in biology and chemical analysis systems. Often filters of various types are used with the aforementioned systems to aid in separation or analysis of samples."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "An aspect of the present invention relates to a nano-filter comprising: a substrate; and at least one nanowire structure on the substrate located between an inlet and an outlet, wherein the nanowire structure comprises a plurality of vertically stacked horizontal nanowires.
"A second aspect of the present invention relates to a method of forming a nano-filter, the method comprising: forming at least one nanowire structure having a plurality of vertically stacked horizontal nanowires on a substrate, the forming of the at least one nanowire structure comprising: forming a plurality of layers of a first material and a second material on the substrate; masking and etching through the plurality of layers of the first material and the second material; and removing the plurality of layers of the second material selective to the first material so as to form the at least one nanowire structure having the plurality of vertically stacked horizontal nanowires; and depositing a capping layer on the at least one nanostructure so as to form the nano-filter.
"A third aspect of the present invention relates to a method of filtration, the method comprising: passing a material through a nano-filter comprising: a substrate; and at least one nanowire structure on the substrate located between an inlet and an outlet, wherein the nanowire structure comprises a plurality of vertically stacked horizontal nanowires; and collecting a filtrate.
"The illustrative aspects of the present invention are designed to solve the problems herein described and/or other problems not discussed."
