Auto-fluorescence is the natural emission of light by biological structures when they have absorbed light. The compounds like Collagen, and Riboflavin, including amino acids like tyrosine, tryptophan, phenylalanine emit the fluorescence signal. Auto-fluorescence increases with cell size. Larger cells have more auto-fluorescence as they contain more auto-fluorescent compounds than small cells.
