The toxicity of Qu, DNPs, and QNPs on PC12 cells. (A) The MTT assay results of Qu; Qu has dose- and time-dependent toxicity on the PC12 cells (a-b, b-c, c-d, d-e, a’-b’, b’-c’, c’-d’, d’-e’, a’’-b’’, b’’-c’’, c’’-d’’, d’’-e’’, and e’’-f’’ have significant differences with *, ****, ***, *, **, ***, *, **, ***, ****, ****, and *, respectively). (B) The MTT assay data of DNPs; DNPs have low toxicity on the cells (a-b, a’-b’, a’’-b’’, and b’’-c’’ have significant differences with *). (C) The MTT assay results of QNPs; QNPs had dose- and time-dependent cytotoxicity (a-b, a’-b’, a’’-b’’, b’’-c’’, c’’-d’’, and d’’-e’’ have significant differences with * and b’-c’ have significant differences with **). *p<0.05, **p<0.01, ***p<0.001, and ****p<0.0001, respectively. n=6, mean ± SEM.
