  1. 1. MOLECULAR ELECTRONICS IIT Bombay Prasanna Kulkarni
  2. 2. Objective Combining Biofunctionality and self assembly principles to form nanoelectronic devices DNA Templates Salmon sperm DNA molecules λ -DNA molecules (48 kbp ~16 μ m ) PCR amplified DNA molecules (150 bp ~51 nm)
  3. 3. AFM images of (a) Salmon sperm, (b) λ -DNA molecules
  4. 4. AFM image 150 bp DNA molecules
  5. 5. Gel picture of PCR amplified DNA molecules 100 bp 200 bp 150 bp ( ~51 nm)
  6. 6. DNA templated nanowires Silver nanowires Silver nanowires formed on the salmon sperm DNA molecules by reducing silver with HQ Nanowires characterized using SEM and TEM SEM EDAX verified the silver on DNA Polymerizing aniline on DNA chemically, polyaniline nanowires formed on the DNA molecules Nanowires characterized using AFM UV-vis, FTIR and Raman Spectroscopy to be used for verification of PANI on DNA Polyaniline nanowires
  7. 7. Silver Nanowires formed on Salmon sperm DNA molecules as observed using (a) SEM and (b) TEM
  8. 8. Polyaniline nanowires formed on Salmon sperm DNA molecules observed using AFM
  9. 9. Thank you
