Figure 7. Fluorescence studies of tau protein upon incubation with SWCNT and MWCNT.

Effects of SWCNT on the fluorescence spectrum of tau protein (A) and MWCNT on the fluorescence spectrum of tau protein (B) at the tau protein concentration of 50 μg/mL (phosphate buffer 20 mM, pH 7.8) and CNTs concentrations of 0, 5, 10, 20, 50, and 100 μg/mL at 25 °C.
