Objectives

  • Analyze AuADA solutions made on 2012/11/27 with UV-vis and AA spectroscopy.
    • Please refer to Keyun Wang's entry for observations on and photographs of the solutions.
  • Resuspend AuADA fibers in solutions made on 2012/11/27 with Tris buffer.

UV-Vis Analysis of AuADA Solutions

  • The spectra of AuADA solutions were collected over 200 nm to 800 nm.
  • 3 mL of AuADA solution was pipetted into a quartz cuvette and then placed in the UV-vis spectrophotometer.

  • A peak at around 520 nm was visible in the spectra of the following mole ratio Au:ADA solutions: 60 through 130. This peak is likely due to the presence of GNPs in these solutions.
