thumb|300px|Micrograph of paper autofluorescing under [[ultraviolet illumination. The individual fibres in this sample are around 10 μm in diameter.]] Autofluorescence is the natural fluorescence of biological structures (autofluorophores) such as mitochondria and lysosomes, in contrast to fluorescence originating from artificially added fluorescent markers (fluorophores).
The most commonly observed autofluorescencing molecules are NADPH and flavins; the extracellular matrix can also contribute to autofluorescence because of the intrinsic properties of collagen and elastin.
