Nanotechnology:
The road for a better future
Prof. Uriel Levy
March 2016
The Nano-concept is in broad use…
… but what is really Nano Science?
Molecule
100,000 smaller
Small isDifferent!
Nano size yields new materials, properties & functions
Human Hair
Nano Science manipulates atoms &
molecules to create new tailored materials
Why Nano?Nano is the only multi-discipline directly
addressing every one of humanity’s challenges
