Feynman quote
Molecular nanotechnology(a.k.a. molecular manufacturing)
What we can make today
What we want
Two ways tocreate new technologies:
Evolutionary
Revolutionary
Developing tomorrow's technology
Working backwards from the goal as well as forwards from the start
Overview of the development of molecular manufacturing
Two more fundamental ideas
Von Neumann architecture
Complexity of self replicating systems
A C program that prints out an exact copy of itself
English translation:
Drexler's architecture
The broadcast architecture
Advantages of the broadcast architecture
Major subsystems in a simple assembler floating in solution
A broadcast method:
Simple pressure actuated device
A proposal for a molecular positional device
Feedstock
A simple binding site for butadiyne
A hydrogen abstraction tool
Some other molecular tools
Synthesis of diamond today:diamond CVD
A synthetic strategy for the synthesis of diamondoid structures
A modest set of molecular tools should be sufficient to synthesize most stiff hydrocarbons.
NASA study on self replication
Replicating brick
"Simple" diamondoid assembler
We could design and model an assembler today. This would:
Rationale for the design of thesimple assembler
Rationale for the design of a simpler system
Disadvantages of Molecular Building Block (MBB) based systems
Diels-Alder cycloaddition
Protein-based molecular building blocks
Can we self assemble a robotic arm?
Can we self assemble a Stewart platform?
Can we self assemble an octahedron?
A Stewart platform is an octahedron in which:
Sliding struts
Sliding struts
Sliding struts
Sliding struts
Can today’s molecular motors be modified so they can be controllably stepped?
Main developmental pathways to molecular nanotechnology
