Scientists Train Nano-’Building Blocks’ to take on New Shapes, as reported in Science

SpecialChem / Sep 5, 2007

Researchers from the University of Delaware and Washington University in St. Louis have figured out how to train synthetic polymer molecules to behave-to literally "self-assemble" -and form into long, multicompartment cylinders 1,000 times thinner than a human hair, with potential uses in radiology, signal communication and the delivery of therapeutic drugs in the human body. The discovery, a fundamental new tool for nanotechnology, is reported in the Aug. 3 issue of the prestigious journal Science. Darrin Pochan, associate professor of materials science and engineering at the University of Delaware, and Karen Wooley, the James S. McDonnell Distinguished Professor of Arts & Sciences at Washington University in St. Louis, led the research effort, which also involved co-authors Honggang Cui, a recent doctoral graduate, and doctoral student Sheng Zhong at UD, and Zhiyun Chen, a doctoral advisee of Wooley's. The research was supported by a Nanoscale Interdisciplinary Research Team (NIRT) grant from the National Science Foundation.
