Representative confocal micrographs show the uptake of nanoparticles in the epithelial and stromal layers of bovine conjunctiva at the end of 4 h transport study at 37 °C using a modified Ussing chamber setup. A, E, and I represent the top, middle, and lower regions of blank conjunctival tissue without any nanoparticle exposure. Corresponding regions for NP (B, F, and J), deslorelin-NP (C, G, and K), and transferrin-NP (D, H, and L) are shown in various panels. Due to folding of conjunctiva, a clear distinction of epithelial and stromal layer could not be made in deslorelin-NP samples. The confocal images were obtained at a magnification of 20X.
