Figure 4

Fluorescence spectroscopy analysis of the PrG tertiary structure in the presence of SWCNT and Gra. Intrinsic fluorescence emission for (A) the PrG and the sonicated PrG alone after 20 min and 2 h, (B) the PrG-SWCNT and (C) the PrG-Gra. The Estern Volmer Equation was determined using various concentrations of acrylamide to calculate the Ksv values in (D) PrG and (E) sonicated the PrG. (E) The Estern Volmer Equation was determined using various concentrations of SWCNT or Gra to calculate Ksv values. Here, the sonicated PrG was added to the figure as a control.
