2 Nanotechnology and Medicine
Ralph C. Merkle, Ph.D. Principal Fellow

3 Health, wealth and atoms

4 Arranging atoms Diversity Precision Cost

5 Richard Feynman,1959 There’s plenty of room at the bottom

6 Eric Drexler, 1992

7 President Clinton, 2000 The National Nanotechnology Initiative
“Imagine the possibilities: materials with ten times the strength of steel and only a small fraction of the weight -- shrinking all the information housed at the Library of Congress into a device the size of a sugar cube -- detecting cancerous tumors when they are only a few cells in size.”

8 Bearing

13 Proposed molecular tools

14 Experimental work H. J. Lee and W. Ho, SCIENCE 286, p. 1719, NOVEMBER 1999

15 Self replication

16 replicating systems (bits)
Complexity of self replicating systems (bits) Von Neumann's constructor ,000 Mycoplasma genitalia ,160,140 Drexler's assembler ,000,000 Human ,400,000,000

17 Micro rotation

18 Exponential assembly

19 Impact Powerful Computers
We’ll have more computing power in the volume of a sugar cube than the sum total of all the computer power that exists in the world today More than 1021 bits in the same volume Almost a billion Pentiums in parallel

20 Impact Nanomedicine Disease and ill health are caused largely by damage at the molecular and cellular level Today’s surgical tools are huge and imprecise in comparison

21 Impact Nanomedicine In the future, we will have fleets of surgical tools that are molecular both in size and precision. We will also have computers much smaller than a single cell to guide those tools.

22 Remove infections

23 Clear obstructions

24 Respirocytes

25 Correcting DNA

26 Cryonics Liquid Nitrogen Temperature Time

27 Nearer term
