“Let us not take it for granted

that life exists more fully in what is commonly thought big

than in what is commonly thought small.”

What is Nanotechnology?



Nanotechnology is the manipulation of matter at


extremely tiny scales (1
-
100nm).




A human hair is approx. 80,000 nm wide



Particles at the
nanoscale

behave differently

Annual R&D Spending on Nanotech



Global Spending for 2005 reached $9.6 Billion.



Japan may surpass the United States in R&D investments
by 2008.

Programmable Metallization Cell (PMC)


S
imilar to thumb drives, but with a terabyte capacity.


Faster and more powerful


Save
energy consumption by more than 99%.




Pro
:

Easy to
manufacture


Con:

The difficulty to fabricate to make finer objects.

Carbon Nanotubes (CNT)



Self
-
arranging C
-
60 molecules


Extreme tensile strength


Superconductivity


Elasticity and resiliency

Are used in data storage devices, such
as Iomega® solutions
REV®

drives/disks


Are incorporated into Nanotube
Compounds (CNT) for industrial use by
companies such as
RTP, NanoMatrix

Let's watch!

Nanodiamond and Drug Delivery


Improved cancer treatment


keeping healthy cells away from toxic drug


Esp. for women, maintaining their healthy look and not loosing their hair


carrying five times more drug because of the large amount of surface
area


Reducing the amount of chemotherapy treatments


In a new research


Formed aggregated clusters of
nanodiamonds


Drug loaded onto the surface of
nanodiamonds


is not active when the nanodiamonds
are aggregated


is active once inside the cell


the clusters break up and slowly release
the drug.

Conclusion


Nanotech will bring great revenue and profits


E.g. Demand for nano/biotech will be $39 billion in 2011
and $82 billion in 2016 in the US



Involved risks


Lack of long term research on the effects of free nano
-
particles in our bodies and the atmosphere.


Difficult to fabricate finer objects in nanoscale
