In-vitro rat skin permeation of lipophilic DID fluorescent dye encapsulated with and without CPP coated NLCN nanoparticles, after 6 h of skin permeation of FNLCN, FNLCNT and FNLCNY formulations the lateral skin sections were made to a depth of 160 µm with cryotome and observed under confocal microscope for skin associated fluorescence. In this figure, the 120 and 160 µm depths skin section figures were not presented because at below 80 µm skin depths we didn’t observe any skin associated fluorescence with all formulations. Vertical row indicate the depth of skin sections.
