In situ mechanical test in the TEM to measure the strength of a 12-nm thick carbon nanotube
Great for research, but not scalable !!!!
Currently: Nano Micro Macro
A self-assembled 2D lattice with alternating rows of hairpins, with restriction site, and 4 nm nanocrystals.
After using a restriction enzyme.
Vertical and horizontal self-assembly of the linking tiles in the second layer using matching hairpins that have been restricted to match the sticky ends remaining on the lattice surface.
Horizontal assembly of the remaining tiles
not directly connected to the previous lattice.
The darker nanocrystals would be made of
material suitable for bits.
The fully assembled lattice, after annealing to finish making the conducting wires.
Scenario for integrated self assembly of
logic device systems
DNA directed assemblies of 5nm and 10nm Gold nanocrystals.
Spontaneous Assembly of
Ribbons of Magnetic Nanorods

An investment in the Molecular Foundry will
provide facility and expertise to at least 300
research groups (funded by all agencies) per year.
This will spare the expense and time of each group setting up its own capability.
In addition it will disseminate know-how and state of the art techniques to research institutions across the USA.
