ZnO NPs hinder the ability of MDA-MB-231 cells to form colonies and undergo metastasis. (A) In vitro colony formation of MDA-MB-231 cells following treatment with ½ IC50 and IC50 values of ZnO NPs for 24 h. (B) wound healing assay of MDA-MB-231 cells after 24 h of exposure to ½ IC50 and IC50 values of ZnO NPs. All data were presented as mean ± SD and analyzed using one-way ANOVA (Turkey’s test); ****P-value signifies < 0.0001, ***P-value signifies < 0.001, **P-value signifies < 0.01, and *P-value signifies < 0.05.
