Figure 6: Far-ultraviolet circular dichroism of HSA determined at pH 7.4 Tris-HCl buffer and constant temperature 25°C. (a) a → d represents CD changes of HSA (Aa), HSA and MTO (Ab), HSA and CHP NPs (Ac), and HSA and MTO-CHP NPs (Ad) at the beginning of complexation. (b) a → c represents the circular dichroism of HSA and MTO (Ba), HSA and CHP NPs (Bb), and HSA and MTO-CHP NPs (Bc) at 15 h of complexation. (c) The ellipticity of HSA at 208 nm corresponding to the reaction time with various substances.
