WHAT DOES NANO REALLY MEAN?
mountain
1 km
1000 m
ant
1 mm
0.001 m
child
1m
0.001 km = 1 m
1,000 mm = 1 m
bacteria
1 m
0.000001 m
sugar molecule
1 nm
0.000000001 m
1,000,000 m = 1 m
1,000,000,000 nm = 1 m
1 m = 1 BILLION nm
1 km = Saturn to Sun
Nanoscale Comparsions
TYPES OF NANO PHENOMENA
gold nanoshells
carbon allotropes
quantum dots
ferro fluids (magnetic)
The Liberty Head gold coin,
depending on condition, would
have a value between $1400
and $3500.
The value of the nanogold in
the vials is a fraction of a
penny. The gold is so small
we need very little of it to use
as a sensor. This is one of
the advantages of using
nanoscale materials.
The Main Electrolytes in Body Fluid
Na+
ClMg ++
Ca++

Sodium Ion
Chloride Ion
Magnesium Ion
Calcium Ion
Potassium Ion

K+
Each ion has its
own rules, and body
movement is a result of the
function of these ions.
