— This invention is the formulation of a SPECT nanoparticle probe for the detection of MMP activity. The surface of a 10 nm-sized gold nanoparticle is functionalized through a thiol anchor with a peptide that is cleaved in the presence of MMP9. The surface is also functionalized with methoxy polyethyl…
