BESAC Questions

  • Nano  Macro

  • Relations to the “Energy” mission of BES

  • Private Sector contact, interest and support

  • Workload of Molecular Foundry management

  • Leverage

Slide3 l.jpg

Nanotube Junction

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

Slide4 l.jpg




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

Molecular Foundry: Leverage labeled with CdSe nanocrystals.

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.
