US Patent 7476596 - Fluidic nanowire alignment

http://www.freepatentsonline.com/7476596.html

This patent from Harvard professor and Nanosys co-founder Charles Lieber teaches a methodology for aligning parallel arrays of semiconductor nanowires via a fluidic flow and transfer process which provides a broader range of substrate materials on which transistors can be fabricated. Claim 1 reads:

1. A method of assembling one or more nanoscale elongated structures on a surface of a substrate, the method comprising acts of:

(A) flowing a fluid that comprises the one or more nanoscale elongated structures onto the surface, which nanoscale elongated structures have at least one portion having a smallest dimension of less than 500 nm; and

(B) aligning the one or more nanoscale elongated structures on the surface to form an array of the nanoscale elongated structures; and

(C) transferring the array of nanoscale elongated structures from the surface of the substrate to a surface of another substrate.
