DNA: May the repository of genetic information become a useful material in molecular electronics? (1/2)

Anna Garbesi

Consiglio Nazionale delle Ricerche (CNR)
CNR - Institute for Organic Synthesis and Photoreactivity
  Italy  






First of two lectures with following content:

  1. The "educated guess" of J. Watson and F. Crick (1953) and the first single-crystal X-ray structure (1980)
  2. Polymorphism of DNA double helices: B-, A- and Z-type structures.
  3. The specificity of natural bases pairing as a designer/building tool
  4. Beyond the double helix by "sticky" guanosine self-assembly: quadruple helices and planar ribbons
  5. Long distance charge transport through DNA oligonucleotides in aqueous buffer solution
  6. DNA enters the material world: the early suggestion of D. Eley and D. Spivey (1962) and the present wealth of experiments
  7. DNA as a scaffold for organizing and interconnecting electronic components into nanoelectronic circuits: self-assembly of an electronic device into a test tube
  8. "Dry" DNA as a conductive wire. Selected exemples of the many, conflicting reports
  9. AFM images of "dried" DNA and Guanosine quadruple helix
second lecture
