MTS viability tests of NIH3T3 cells treated with ZnO NPs doped with variable Mn2+ nominal concentrations (50, 500 and 2000 ppm) at different NPs concentrations (1, 2, 4, 8, 16, 32, and 64 µg/mL): (a) NPs prepared with PVP; (b) NPs prepared with SHMTP. All values were normalized to the control (0 µg/mL NPs).
