Wound edges were marked with lines. Amplification, ×100. a The wound-healing width was observed at the indicated time after the treatment of SeNPs@Am. b The cell motility of the control and treated HepG2 cells was quantitatively analyzed at 24 h. c The effect of SeNPs@Am, Am, and SeNPs on the migration of HepG2 cells. d The inhibition rate of migration of control, SeNPs@Am, Am, and SeNPs, respectively. Data represent the mean ± SD of three independent experiments. **p < 0.01, ***p < 0.001 vs. the control
