Molecular Foundry Workshop

1
Molecular Foundry Workshop
Purpose Forum for scientific feedback as a
necessary step in developing the center for
governmental funding approval

• One of 3 new nanotechnology centers in the US
  developed through the nanotechnology initiative
• Center for Nanophase Materials Sciences (Oak
  Ridge, TN)
• Center for Integrated Nanotechnologies (Los
  Alamos/Sandia, NM)
• To be completed in 2006
• Designed to be a user facility for governmental,
  educational, and industrial usage
• Emphasis on training of first generation of
  nanoscientists

Six Facilities at the Molecular Foundry

• Inorganic Nanomaterials
• Organic, Polymer/Biopolymer Synthesis
• Theory
• Nanofabrication
• Biological Nanostructures
• Imaging and Manipulation
• Emphasize multidisciplinary approach
  collaboration amongst facilities

  absorption

4

• Organic, Polymer/Biopolymer Synthesis (J. M. J.
  Frechet)
• Site-assisted self-assembly growth of structures
  based on polymers and biomolecules
• User-run experiments (synthesis, molecular
  assembly characterization)
• Organic synthesis, combinatorial synthesis,
  polymer synthesis, hybrid materials

  function

6

• Theory II (S. G. Louie)
• Challenges-
• Quantum confinement new properties and
  phenomena
• Property sensitivity to size, symmetry, and
  structure
• Degrees of freedom
• Different length scales at the nanoscale

7

• Nanofabrication (J. Boker)
• Utilizing microfabrication techniques for
  nanoscale applications
• Top-down approach
• E-beam, focused ion-beam, optical soft
  lithography, resist processing, film deposition,
  plasma etching, wet etching
• Allowance of unwelcome materials for standard
  microfabrication
• Examples - Nanofabrication of catalysts
  - Nano-MOSFETs - Decoder array
  chip for nanodevices

8

• Biological Nanostructures (C.R. Bertozzi)
• Nature builds devices from nanoscale components
• Biological components into devices
• - Molecular motors- Structural assemblies-
  Cell-based biosensors- Biocompatible/Biodegradabl
  e materials
• DNA- directed assembly of nanocrystals
• Example Patterning Cells onto Chips

9

• Imaging and Manipulation (M. Salmeron)
• LT-STM, LT-AFM, NSOM, Combined SEM and STM/AFM
  with nano-manipulators, single molecular
  microscopy, analytical transmission electron
  microscopy, confocal microscopy
• Microscopes with in-situ manipulators
• Optical imaging and spectroscopy
• Imaging of very soft matter (bio-materials,
  liquids)
• Building and manipulating single atom and
  molecule
• Expanding on standard available techniques to
  develop specialized new equipment for specific
  applications

10

• Feedback and Conclusions
• Long time until Molecular Foundry opens
• Ramp-up time Until 2006 opening?
• Cost policy no user cost (supported by DOE)
• Possible fellowships for users (travel/housing
  stipends)
• Outreach Programs
• Intellectual property
