Notes

  • A stir bar was placed in the reaction mixture. In the future, this will not be added.
  • In comparison to the previously prepared solution, the solution remained a dark green color.
  • The solutions prepared on 01/28/2014 changed into a dark blue color. This is indicative of the preparation of magnetic magnetite particles.
  • A conglomeration of various fiber-esque precipitate formed in all of the prepared BSA:AuNP:MagnetiteNP solutions. Large particles also appear to be present. In comparison to the previously prepared protein fibers, these fibers appear much smaller (not as long or wide). The solutions will be filtered and these potential fibers will be collected for analysis.
  • The temperature of the hot water bath remained a 75-85°C. The temperature never reached 90°C.
