Fabricating with in 1-100 nm.
Multi-disciplinary field of nano.
Extension of existing science.
Plenty of room at the bottom - Richard Feynman.
STM & cluster science in early 80’s.
CONCEPTS OF NANO :CONCEPTS OF NANO 1 nm = 1 billionth of a meter
usage in physics , chemistry , biology
space research
In medicine
Future’s future
APPROACHES :APPROACHES Bottom up approach
* they arrange smaller components in to more complex.
Top down approach
* create smaller objects using Larger objects
NANO MATERIALS :NANO MATERIALS Applications with morphological features less than one tenth of a micrometer
