 Note About Images

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.

Mirkin and his colleagues were supported in part by the National Science Foundation (NSF), and are publishing their discovery in the 16 January 2004 issue of the journal Science. A press release detailing their work is available from Northwestern.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering, with an annual budget of nearly $5.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 universities and institutions. Each year, NSF receives about 30,000 competitive requests for funding, and makes about 10,000 new funding awards. The NSF also awards over $200 million in professional and service contracts yearly.
