Figure 7.

Confocal laser scanning microscopy images of receiver medium from the skin penetration study of NaFl-loaded, Rh-PE-labeled ultradeformable liposomes at different time points.

Notes: (A) 30 minutes; (B) 1 hour; (C) 2 hours; (D) 4 hours. Each image is divided into four parts: -1, green fluorescence of NaFl; -2, bright field image; -3, red fluorescence of Rh-PE; -4, overlay of -1 and -3. Scale bars represent 100 μm.

Abbreviations: NaFl, fluorescein sodium; Rh-PE, rhodamine B 1,2-dihexadecanoyl-sn-glycero-3-phosphoethanolamine triethylammonium salt.
