(A) Cell viability of PC12 incubated with 1 and 1+Van after 5 days, [1]0 : [Van]0 = 1 : 1. (B) IC50 values of 1/Van against PC12 cells after 5 days at different conditions: 1 incubated with PC12 cells for 12 h, either adding Van or changing medium (↔) abrogates the cytotoxicity of the nanofibrils. TEM images of (C) solution of 1 and (D) mixture of 1 and Van, inset are corresponding optical images under UV irradiation, [1]0 = [Van]0 = 500 μM (enlarged Fig. 2B in Fig. S2).
