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.

Resuspension of ADA Fibers

• Tris buffer was made on 2012/09/04.
• Please refer to Keyun Wang's entry for volumes and concentrations of Tris buffer added to
