(A) SKOV-3 cells and (B) NCI/ADR-RES cells incubated with free Cur or Cur/PLGA NPs for 3 hours. Free Cur entered both SKOV-3 and NCI/ADR-RES cells. Cells incubated with Cur/PLGA NPs also showed intracellular fluorescence signals. Cur: green fluorescence signal from Cur; Nu: nuclei stained with Draq5; Tm: transmission image; Overlay: overlay of NP, Nu and Tm. Magnification: 600×. Each scale bar = 40 µm.
