  1. Add 1 μL of diluted thiol-modified TS primer to 5.6 mL of citrate AuNP solution.
  2. Mix 3 μL TS primer (no AuNP), 1 μL 50x dNTP mix, 16 μL sterile water, 2.5 μL 10x PCR buffer, and 2 μL cell extract in a PCR tube.
    • Cell dilutions used: 400000, 200000, 100000, 50000, 25000.
  3. Incubate in heat block at 30°C for 30 min.
  4. Add 6.10 μL molecular beacon.
  5. Incubate in heat block at 37°C for 1 hr.
  6. Take fluorescence spectra.


  • Fluorescence data of solutions using just the primer instead of primer/AuNP:

  • Fluorescence of solutions without AuNP vs. citrate AuNP solutions synthesized on 06/14/12:

Changes in citrate AuNP fluorescence most likely due to photo-bleaching of MB over the weekend.
