Self Assembled DNA Nanostructures

admin — Fri, 14 Dec 2007 04:01:02 -0600

by: admin

Description: Description Self-Assembled DNA Nanostructures. (A) DNA �tile� structure consisting of four branched junctions oriented at 90� intervals. These tiles serve as the primary �building block� for the assembly of the DNA nanogrids shown in (B). Each tile consists of nine DNA oligonucleotides as shown. (B) An atomic force microscope image of a self-assembled DNA nanogrid. Individual DNA tiles self-assemble into a highly ordered periodic two-dimensional DNA nanogrid.
