In fluorescence‐based assays, the autofluorescence of capture surfaces produces strong background noise. In article number 1803751 , Amos Danielli and co‐workers use photobleaching as a method to reduce the autofluorescence of magnetic beads, a commonly used capture surface. The technique yields a 3‐fold improvement in the limit of detection and signal‐to‐noise ratio of a fluorescence‐based immunoassay.
