Nanoparticles that not only mediate functional delivery of therapeutic payload, but also allow monitoring of delivery by MRI are of great interest. Here we describe liposome nanoparticles incorporating a Gd labelled peptide, that act as 'switchable' MR contrast agents, in that upon delivery of the DNA payload inside the cell the signal is enhanced.
