Figure 4. Skin dosed with Baa-Lys(FITC)-NLS for 24 hr

Confocal scanning microscopy images of skin dosed with Baa-Lys(FITC)-NLS for 24 hr; top row: Confocal-DIC channel image shows an intact stratum corneum (SC) and underlying epidermal (E) and dermal layers (D). Middle row: Baa-Lys(FITC)-NLS fluorescence channel (green) and confocal-DIC channel show fullerene penetration through the skin. Bottom row: Fluorescence intensity scan of Baa-Lys(FITC)-NLS; all scale bars represent 50 μm; reproduced with permission from Reference 19.
