US Patent 7611562 - Triangular nanoframes

http://www.freepatentsonline.com/7611562.html

This patent comes from Chad Mirkin's group at Northwestern University. The patent teaches methodology used to fabricate a new type of nanostructure called a "nanoframe" which is useful to investigating how nanoscale shapes effect the bulk physical and chemical properties of substances. Claim 1 reads:

1. A method of forming a triangular nanoframe comprising etching a nanoprism with a salt to form a nanotriangle.
