Anti-metastatic potency of DS–CuO NPs compared to DS–Cu in MDA-MB 231, A549 and Huh7 cells. a Microscopic images of the healed wound in the untreated and treated cells at 0 and 24 h (magnification, 40 ×; scale bar, 200 µm) with b Relative migration inhibition % in DS–CuO NPs- and DS–Cu-treated cells to the untreated cells. c The percentage inhibition of MMP9 in DS–CuO NPs- and DS–Cu-treated cells relative to the untreated cancer cells. Data (mean ± SEM), DS–CuO NPs was compared to DS–Cu and considered significantly different at p <  < 0.05*, < 0.005**, < 0.001***
