Cell viability of PC12 cells treated with quercetin (A), Cs@Se NPs (B), Tw-Cs@Se NPs (C), and Q-Tw-Cs@Se NPs (D), cisplatin (E) after 24 h. Each value is represented as mean ± SD, n = 3. A one-way ANOVA was used for statistical comparison among groups, followed by Dunnett’s’ post-test, and statistical significance is denoted as follows: *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001.
