IN PRINT: Directed
nucleation assembly of DNA tile complexes for barcode-patterned lattices
The programmed self-assembly
of patterned aperiodic molecular structures is a major challenge in
nanotechnology and has numerous potential applications for nanofabrication of
complex structures and useful devices. Here we report the construction of an
aperiodic patterned DNA lattice (barcode lattice) by a self-assembly process of
directed nucleation of DNA tiles around a scaffold DNA strand.

Duke University researchers have
moved the bottom-up method a step forward by programming strands of synthetic
DNA to self-assemble into a structure that makes the pattern encoded in a DNA
strand readable by microscope.

MOLECULES ARRANGED TO ACT LIKE INFINITESIMAL DATA DISPLAY: Computer scientist uses synthetic DNA to
pattern computer displays
Duke University computer
scientists have induced DNA molecules to order themselves into the equivalent
of a Lilliputian computer display. Using a synthetic DNA strand as input, the
method caused the self-assembly of tile-like DNA structures displaying binary
data 01101. By changing the input DNA, the method displayed a different value,
10010.
