Figure 1: Optimized tumour-activated nanoparticle-based sensors, consisting of a nanoparticle (NP) core decorated with a protease-cleavable substrate and tumour-targeting ligands.
Figure 2: Tumour-activated imaging probe with signal amplification, driven by the conversion of the probe's precursor form into the reporter form.
