Objective

To take UV-vis data of tris + 50 mM tris buffer (pH 10.1) mixed on 02/15/12.

Description

  1. Centrifuge AuNP fibers + 50 mM tris solution made on 02/15/12.
  2. Take UV-vis absorption data.
  3. Compare data to that obtained on 02/15/12 and 02/21/12.

Data

  • Graph of absorbance vs wavelength over time for the AuNP fibers + 50 mM tris after centrifuge:

Overall absorbance decreased this week, however it appears that the peak wavelength has continued to shift lightly towards shorter wavelengths.
