Future Work

• Begin electrical measurements of variety of
  samples, particularly those coated with MoGe, a
  superconducting alloy. Measure conductivity at
  various temperatures and ambient magnetic fields.
• Use anti-clumping agents to produce single DNA
  wires of greater length.
• Explore reason for linear form of DNA across
  trenches.
• Create more complex arrangements of DNA through
  self assembly and metallize to form electrical
  constructs.

Pair of wires, 4 nm MoGe on ? DNA, width 10 nm.
This sample is undergoing electrical measurements
(but not yet ready for presentation).
