There appears to be an increased potential for conflict as
a rapidly growing world population tries to sustain itself with limited
natural resources.2 The disparity in wealth between developed and developing
nations, in combination with the uneven distribution of natural resources,
remains a threat to the stability of states and of the international system.
With the advent of modern manufacturing, advanced technologies, and the
information age, the importance of natural resources has been reduced
for developed nations.
Nanotechnology may fall into the category of disruptive technologies where
significant new capabilities and industrial systems bring large-scale
changes, which may result in the betterment of society or may create new
problems. technologies, materials.

WILMINGTON, Del., Dec. 2, 2003 --- A collaborative group of
DuPont-led scientists have discovered an innovative way to advance electronics
applications through the use of DNA that sorts carbon nanotubes.
This research in the emerging field of nanotechnology appears in the current
issue of the journal Science, which is published by the AAAS -- the world's
largest general scientific organization.
Initially, DuPont Central Research & Development scientists found
that singlestranded DNA strongly interacts with carbon nanotubes to form
a stable DNA-carbon nanotube hybrid that effectively disperses carbon
nanotubes in an aqueous solution.
As a follow-up to that initial work, a multidisciplinary team of scientists
from DuPont, the Massachusetts Institute for Technology (MIT) and the
University of Illinois worked together to discover a new method for separating
carbon nanotubes using single stranded DNA and anion-exchange chromatography.

"Houston is already a leader in the newest technology
craze: Nanotechnology.
The $10.5 million grant that Rice recently received to create a Center
for Biological and Environmental Nanotechnology will only augment Houston's
leadership on the nanotech front.
But to transform this exciting research into commercial ventures, Houston
also needs to develop an infrastructure within the investment community
to fund emerging Nanotech companies.
