A novel molecular probe for enzymatic activity with a dual output detection-mode has been developed. The probe effectively detected the presence of the bacterial protease penicillin-G-amidase; a single cleavage by the enzyme initiated the fragmentation of a self-immolative dendritic platform to release two reporter units. The signals of the free reporters were detected by two different spectroscopic techniques, fluorescence and UV-vis. This is the first reported molecular probe with two different chromogenic reporter units activated by a specific stimulus.
