(A) CLSM images of A549 cells incubated with free cou solution, Cou-SLNs and Lf-Cou-SLNs for 4 and 24 h (Magnification 63X, Scale bar, 25 µm); (B) Normalized fluorescence intensity recovered from A549 viable cells after 24 h treatment with free dye, Cou-SLNs or Lf-Cou-SLNs. Statistically significant differences from Lf-Cou-SLNs and Cou-SLNs to untreated cells (p < 0.05); (C) 3D-time laps confocal images of the cellular uptake of Lf-Cou-SLNs in A549 lung cancer cells after 24 h (Z-stacks 14 µm, Scale bar, 25 µm).
