Far-UV CD spectroscopy of the PrG secondary structure under different conditions. (A) Far-UV CD of the PrG (200 µg/ml) and sonicated PrG alone after 20 min and 2 h. Far-UV CD measurement for the PrG in the presence of various concentrations of SWCNT and Gra after (B) 2 h and (C) 24 h. Here, sonicated PrG was added to the figure as a control.
