* After 24 hours, no purple fibers were formed, thus it can be concluded that the addition of salt into solution interacts with gold nanoparticle aggregation in a way that disrupts the aggregation. The lack of precipitation after 24 hours can be due to the gold nanoparticles being more stable when interacting with Tris buffer. | * After 24 hours, no purple fibers were formed, thus it can be concluded that the addition of salt into solution interacts with gold nanoparticle aggregation in a way that disrupts the aggregation.

* A purple homogenous solution was yielded after the addition of Tris buffers at all three concentrations used. Thus, it can be safe to conclude that Tris buffer at pH 10.0 can successfully resuspend fibers at a 6:1 ratio of solution to tris buffer. | * A purple homogenous solution was yielded after the addition of Tris buffers at all three concentrations used.
