Good afternoon. I'd like to thank you all for attending and
making this such an exciting event.

2. Medicine
CAT scan

3. Detect minute amounts of
Medicine
current state of the art:
Detect 109 cancer cells.
What if…
Detect minute amounts of
cancer cells.

4. Detect minute amounts of
Medicine
What if…
Detect minute amounts of
foreign material.

5. Medicine
Radiation therapy

6. Medicine What if… Target only the disease.
Administer a small dosage directly to the disease.

7. Electronics

8. Electronics What if… Circuits which can build themselves.
Transistors which are ~100 to 1000
times smaller than current transistors.
source VG
drain
island
Circuits which can build themselves.

9. Build from the “bottom up”.
Nanotechnology
Philosophy
Build from the “bottom up”.
Fabricate structures atom by atom (or molecule by molecule) with fundamentally new properties and/or functions.

10. Length Scales 1 nanometer = one billionth of a meter (10-9 meters)
Gate length of
a transistor
~ 130nm
Diameter of a human hair
~ 100,000nm
Protein
~ 50nm

11. Over $5 billion worldwide in government funding.

National Institute for
Nanotechnology (Alberta)
$120million for 5 years
