US Patent 7955644 - Selective anchoring of nanoscale structures

http://www.freepatentsonline.com/7955644.html

This patent from the California Institute of Technology discloses a new method of  patterning nanostructures such as carbon nanotubes on a substrate which may have use in fabricating field emission displays. Claim 1 reads:

1. A method for fastening a plurality of nanoscale structures within an anchoring layer, comprising acts of:

providing a first fluid layer on an anchoring substrate;

providing a plurality of nanostructures on a growth substrate on which the nanostructures were grown, the nanostructures each having a defined height and orientation with respect to the growth substrate; and

introducing the plurality of nanostructures to a desired depth in the first fluid layer, such that the orientation of the nanostructures relative to the growth substrate is substantially maintained.
