Abstract

A probe that allows specific 'painting' of human tumours is described. Probe activation was mediated by specific matrix metalloproteinases, resulting not only in disruption of a FRET pair, but in the generation of a fragment that "fluorescently paints" human tumours. This probe demonstrated rapid and effective human tumour labelling with the potential to allow margin detection during surgical resection.
