The invention concerns the field of molecular probe architecture for in vivo imaging. More particularly, the invention concerns molecular constructs providing an imaging function activable in intracellular environment, said constructs being further bound to a vector which enables certain cells to be targeted, and said cells to be internalized. The inventive fluorescence probes enable in particular images of certain targeted tissues to be formed, while maintaining a low background noise level and, preferably, while obtaining at the targeted tissue, an imaging signal increasing in time.
