Novel Lutein Loaded Lipid Nanoparticles on Porcine Corneal Distribution

Figure 5

Lutein distribution in porcine cornea after 24 h treatment observed by using confocal laser scanning microscopy. Lutein fluorescence emitted at 515 nm was recorded when excited at a wavelength of 488 nm by means of an argon laser. The sample was scanned from the tissue surface (0 μm) to a depth of 352 μm at a 29.3 μm interval.
