BESAC Questions

Nano Macro

Relations to the “Energy” mission of BES

Private Sector contact, interest and support

Workload of Molecular Foundry management

Leverage

Currently: Nano Micro Macro

Nanotube Junction

In situ mechanical test in the TEM to measure the strength of a 12-nm thick carbon nanotubeGreat for research,

but not scalable !!!!

Scenario for integrated self assembly oflogic device systems

A self-assembled 2D lattice with alternating rows of hairpins, with restriction site, and 4 nm nanocrystals.

A.

After using a restriction enzyme.

B.

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.

C.

Horizontal assembly of the remaining tiles not directly connected to the previous lattice. The darker nanocrystals would be made of material suitable for bits.

D.

The fully assembled lattice, after annealing to finish making the conducting wires.

E.

First Steps Toward Functional Systems of Nano-building Units

DNA directed assemblies of 5nm and 10nm Gold nanocrystals.

Spontaneous Assembly ofRibbons of Magnetic Nanorods

Inorganic Nano-Crystals: Self Assembly & Organization

Molecular Foundry: Leverage

An investment in the Molecular Foundry willprovide facility and expertise to at least 300research 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.
