Single-Strand DNA Tiles and Crystals
単鎖DNAタイルとその結晶について

Abstract: Central to the success of much emerging DNA structural
nanotechnology is the concept of the DNA tile. Assembled from a number of
synthetic single-strand DNA, a conventional tile has a rigid structural core
and several affinity encoding sticky ends that guide the tiles to assemble
into crystal structures. A key open question is: what is the minimal form a
DNA tile? A natural answer would be a tile that is void of the structural
core and contains only the affinity bearing sticky ends. I describe in this
talk a set of such simplistic tiles, each of which is a short flexible
single strand DNA. These single-strand DNA tiles assemble into crystals of
1D (chains) and 2D (ribbons, tubes) connectivity. Of particular interest is
the kinetic-trapping based construction of molecular tubes with precisely
programmed circumferences.

Biography: Peng Yin is a post-doctoral scholar at California Institute of
Technology. He is affiliated with Caltech's Center for Biological Circuit
Design, Department of Computer Science, and Department of Bioengineering. At
Caltech, he works primarily with Prof. Niles Pierce and Prof. Erik Winfree.
His current research interests focus on engineering self-assembled nucleic
acid molecular devices and structures. He received a B. S., Biochemistry &
Molecular Biology, Bachelor of Economics, Peking University, China, 1998; M.
S., Molecular Cancer Biology, Duke University, 2000; Ph. D., Computer
Science, Duke University, 2005.
