Figure 1: The graph above is a UV-Vis calibration curve relating absorbance of Rhodamine B at 556 nm when dissolved in AuNP fiber supernatant to the concentration of Rhodamine B. The equation of the line is included on the graph. The high R2 value indicates the strong fit of the trendline/equation to the data.
Figure 2: The table above shows the raw and calculated data including the peak absorbance, the concentration that this absorbance corresponds to, the change in concentration after incubation, and the percent change in concentration.
Figure 3: The chart above displays the percent change in concentration of Rhodamine B in solution after incubation for 2 hours. Blue bars correspond to 10 μM initial Rhodamine concentrations, red bars correspond to 5 μM initial Rhodamine concentrations, and green bars correspond to 2 μM initial Rhodamine concentrations. As expected, the concentration of Rhodamine B in solution decreases indicating that Rhodamine B is likely being incorporated into the AuNP fibers.
