Figure 7

Fluorescence images (400x magnifications) of DCFH-DA stained (A) MDA-MB-231 and (B) MCF-7 cells showed the effect of drugs and different nanoformulations on ROS generation due to loss of Δψm. CPMSNs treated cells stained with DCFH-DA showed increased fluorescence intensity of DCF, which is proportional to the amount of ROS produced by the (C) MDA-MB-231 and (D) MCF-7 cells. The Data represent mean ± SD *p ≤ 0.05 was considered statistically significant.
