The cell viability tested by MTT method as a function of Se nanobelt concentration and time. (a) Cell viability of HeLa cells in MTT test, cultured with different concentrations of Se nanobelts for 12, 24, and 48 h. (b) Viability of L929 cells in MTT test, cultured with different concentrations of Se nanobelts for 12, 24, and 48 h.
