Nanoscale Building Blocks Form Spheres, Tubes and Curves
Self-assembling structures could find wide use in nanoelectronics and drug delivery
Inspired by the molecular assembly techniques used in living cells, chemist Chad Mirkin and his colleagues at Northwestern University have created a new class of nanometer-scale building blocks that can spontaneously assemble themselves into ultra-tiny spheres, tubes and curved sheets. This is the first time that scientists have been able to make structures on this scale that curve in any fashion, as opposed to being straight or flat. Since the Mirkin group can also control the size and curvature of their structures very accurately, the technology could eventually lead to important applications in nanoscale electronics and drug-delivery systems.

NSF Sponsors Day-Long Nanoscience and Engineering Symposium
The National Science Foundation (NSF) hosted
leading researchers on March 19 at "Small
Wonders," a day-long symposium and exhibition
of nanoscale science and engineering.
In opening remarks, NSF Director Rita
R. Colwell reviewed the increasing role
of NSF investments. Several segments of
the event, including the keynote address
by Richard Smalley, Nobel Laureate and
Rice University professor, and a panel
of leading researchers discussing "Issues
and Implications of Nanotechnology for
Society" were webcast live and accessible
to audiences over the Internet.
