* TRIS Desired pH 9; Looks like the CHES ratios. Looks like control. The only deviation is exhibited ion the 110:1 ratio in which the fibers appear redder. This is either due to more fibers being formed or could be the breakdown of the fibers due to the increased color of the solution. | * TRIS Desired pH 9; Looks like the CHES ratios.

*EDTA; Looks very similar to the controls; however, the fibers became more red in the 50:1 with fibers and the 110:1. | |||

* 2,2 bipyridine caused all AuNP's to fall out of solution to form fibers. | |||
*Salicylic Acid wasn't that much different than the controls; however, the 50:1 with fibers and the 110:1 sample the fibers appeared more red. | |||
*Sodium Chloride caused all fibers to fall out of solution. The fibers weren't that abundant. | |||

**Note that the 50:1 ratio without fibers wasn't available for this test. | |||
*Potassium Chloride caused all fibers to fall out of solution. What is odd is the fibers don't seem numerous. | |||

*Magnesium Chloride caused all fibers to fall out of solution. What is odd is the fibers don't seem numerous. | |||

*Chloroform; Looks very similar to the controls. This samples was a little odd because we originally thought chloroform was water soluble. It isn't. As a result a separation of layers was observed, and the fibers wouldn't go into the chloroform layer. | *Chloroform; Looks very similar to the controls.

*DMSO has no measurable differences from the controls. | |||
*DMF has no measurable differences from the controls. | |||
*Acetone has no measurable differences from the controls. | |||
*SDS looked slightly different. In the 50:1 ratio with fibers and the 110:1 ratio the fibers appeared redder than the controls an more abundant. Perhaps this is the beginning of the fibers going back into solution? | |||
