Not
all libraries contain books. In chemistry, the word
library is used to refer to a collection of molecules.
University of Oregon chemist Jim Hutchison's new
way of rapidly generating libraries of tiny particles
with great promise for research and development at
the nanoscale is featured on the cover of the Sept.
5 issue of Inorganic Chemistry.
"We've discovered a method for generating a diverse
library of functionalized gold particles quickly
and easily," said Hutchison, who directs the university's
Materials Science Institute. "Basic research of this
type is the key to finding out what kinds of new
electronic, optical and pharmaceutical products actually
will come to market."
The article describes how to synthesize the versatile particles, built with cores
of 11 gold atoms, and discloses their properties. Nanomaterials and technologies
are projected to become a trillion dollar industry by 2010 and affect every industrial
and consumer product sector, Hutchison said.
One of the keys to understanding the size-dependent properties and applications
of nanoparticles is generating libraries of particles with different sizes for
physical study. Earlier this year, Hutchison's laboratory reported success in
generating a similar library of larger particles, with cores having about 100
gold atoms, in the Journal of the American Chemical Society. The 11-atom and
100-atom libraries span a size range of 0.8 to 1.5 nanometers, a range of particular
interest to nanoscientists and technologists.
Hutchison co-authored the Inorganic Chemistry article
with Gerd Woehrle, one of his doctoral students.
Woehrle is now finishing post-doctoral work at the
Max Planck Institute in Germany.
Already known as world leaders for encouraging the
teaching of green chemistry principles, Hutchison
and his Oregon colleagues are pioneering the field
of green nanoscience. His role in laying out the
conceptual template for how to design "green" or
environmentally-benign nanosubstances was described in the March issue of Environmental
Science & Technology.
Hutchison is a member of ONAMI, the Oregon Nanoscience and Microtechnologies
Institute. The National Science Foundation, the Alfred P. Sloan Foundation and
the Camille and Henry Dreyfus Foundation, Inc., have funded his research.
