Figure 6. Near UV-CD spectra of tau protein during incubation with SWCNT and MWCNT.

Near UV-CD spectra, recorded for SWCNT-tau protein (A) and MWCNT-tau protein (B) at the tau protein concentration of 500 μg/mL (phosphate buffer 20 mM, pH 7.8) and CNTs concentrations of 0, 5 10, 20, 40, 60, 80, and 100 μg/mL at 25 °C. The DC₅₀ for SWCNT/tau and MWCNT/tau interactions was 21.7 and 53.2 μg/mL, respectively (C).
