Defining nanoscale science and engineering (“nanotechnology”)
Why the excitement about nanotechnology? Examples of “nanotech” in current research … and everyday life
U.S. National Nanotechnology Initiative and NSEE
Examples of NSEE research
The study of materials and associated
physical, biophysical and biochemical
phenomena on the scale of ~1-100 nm.
The primary appeal of nanotechnology is the
potential to manipulate matter at
the nanoscale. This leads to the
possibility of preparing novel materials
(nanomaterials) that have specific,
manipulable physical properties and

Areas in which nanotechnologies are expected to impact our everyday lives:
Federal R&D program that coordinates multiagency efforts in nanoscale science, engineering, and technology.
Launched in 2001 after approval by U.S. Congress in November 2000 ($422 million in funding, 2001 fiscal year)
23 federal agencies comprise the Initiative, 11 of which have a nanotechnology R&D budget.
2004 fiscal year … $961 million in funding; 2007 fiscal year …. ~$1,445 million in funding; 2009 budget, $1.5 billion in funding
