Objective

  • Take images of each treatment and standards.
  • If no treatment reverses fiber formation, fibers will be extracted from 50:1 and 110:1 ratios to expose them directly to each treatment.
  • If a treatment reverses fiber formation, it will be investigated further in order to find the smallest amount of the variable that can be added to solution in order to cause fiber degradation.
  • More treatments of 2,2 bipyridine will be prepped to see if ability to precipitate fibers is observed again.
  • Synthesize 110:1, 50:1, and 40:1 lysozyme-AuNPs
  • Synthesize 100:1 BSA-AuNPs and test various treatments.

Procedure

Creating Stock Solutions of Gold, Lysozyme, and BSA

  • As seen below, each stock solution was created following the calculations in the table.
  • Each solution was created using a volumetric flask and deionized water.


Synthesizing Lysozyme-AuNPs and BSA-AuNPs

  • As seen below, each solutions was created using the following calculations.
  • We made five tubes of each ratio.

Images

Notes

  • There are two samples of 50:1 because one set of samples made fibers, whereas the other did not. This can be seen in the controls. We believe this occurred because between ratios 40:1 and 50:1 the changeover to fibers occurs very quickly. As a result, even measurements slightly off could switch the balance. Due to this point this is why we've decided to change our AuNP's ratios in order to stay a little bit further away from this turning point.
