    Two optical signatures of amyloid fibres—luminescence in the blue and a near-infrared signal, which can be observed in in vitro and in vivo tissues—are reported. The findings allow for staining-free characterization of amyloid deposits in human samples and could open the door to innovative diagnostic strategies for neurodegenerative diseases.
