What is Nanotechnology
Nanotechnology is the creation of functional materialsdevices and systems through control of matter on thenanometer length scale exploiting novel phenomena and
properties (physical chemical biological) present only at thatlength scale
bull What is the ldquonanometer length scalerdquo bull What ldquonovel phenomenardquo are present on the nanoscale
bull How could we ldquocontrol matterrdquo on the nanoscale
And importantly
bull Why is this all so exciting
