DNA Printing

I read two books this summer that have sensitized me (further) to bio-it convergences.
Radical Evolution by Jarreau
Fab by Gershenfeld.

Here's one such convergence, from NASAtechbriefs.

Researchers at the Massachusetts Institute of Technology (MIT) have
developed a nanoscale printing technique that could make DNA analysis
as common as a blood test.

The technique - called supramolecular nano-stamping -- prints DNA from
one substrate, such as glass, gold, or silicon, onto another. Using a
print template, mirror-image copies can be produced in a few steps,
offering the rapid transfer of a large amount of information.

The technique could be used to produce other types of nanodevices
including organic and inorganic materials. DNA could be used as a
starting material to produce a transistor or a semiconductor,
according to MIT materials scientist Francesco Stellacci.
