2. NANOTECHNOLOGY 
A nanometer is a unit of length in the
metric system which is equal to one
billionth of a meter (10^9). 
Technology is the making, usage, and
knowledge of tools, machines and
techniques in order to solve a problem or
perform specific function.

3. It refers to the constructing and engineering of the
functional systems at very micro or atomic level. 
It is a field of applied science and technology whose
unifying theme is the control of matter on the molecular
scales, and the fabrication of devices within that size range.
It is a highly multidisciplinary field combined with refined
processes such as beam lithography and molecular beam
epitaxy that allow the deliberate manipulation of
nanostructures which led to the observation of novel
phenomena.

6. Nanotechnology refers to the manipulation of
matter on an atomic or 
subatomic scale.

7. On the nanometer-scale, materials may
exhibit unusual properties.
In nanometer-scale particles, the
arrangement of atoms reflects light
differently. (e.g.: gold can appear dark red
or purple, while silver can appear
yellowish or amber-colored)

8. "Nanotechnology is not simply
working at ever smaller
dimensions. Rather, working at
the nanoscale enables scientists
to utilize the unique physical,
chemical, mechanical, and optical
properties of materials that
naturally occur at that scale."

9. Historical BackgroundHistorical Background
The concept of
nanotechnology was
popularized by Richard
Feynman in 1959. Since then,
advancements in materials
science and quantum physics
have propelled the field
forward, leading to innovative
applications that were
previously unimaginable.

11. A nanoparticle is a small particle that ranges
between 1 to 100 nanometres in
size. Undetectable by the human eye,
nanoparticles can exhibit significantly
different physical and chemical properties to
their larger material counterparts.

13. Approaches of
Nanotechnology
Nanotechnology can be seen as an extension of existing
sciences into the nanoscale, or as a recasting of existing
sciences using a newer, more modern term.

14. Bottom-up Approach, materials and devices are built
from molecular components which assemble
themselves chemically by principles of molecular
recognition.
Top-down Approach, nano-objects are constructed
from larger entities without atomic-level control.

15. Bottom-up approach: You start with tiny bricks
(molecules) and let them naturally stick together
(molecular recognition) to form the walls, then the
house. 
Top-down approach: You start with a big block of
wood (larger entity) and carve out the shape of the
house. 
Both approaches make a house, but the bottom-up method is
more precise and allows for more complex designs at the
molecular level.
