Figure 2. Allium cepa chromosome aberration analysis of biogenic silver nanoparticles (AgNP-T) at different concentrations, with 24 h of exposure.

(A) Normal anaphase at 40x magnification (A1, A2, and A3 alterations); (B) Normal metaphase at 40x magnification (B1, B2, and B3 alterations); (C) mitotic index and DNA alteration index. Different letters indicate different comparisons and different numbers indicate significant differences (p < 0.05).
