A gold nanoparticle was radiolabeled with 125I and 111In and functionalized with an MMP9-cleavable peptide to form a multispectral SPECT imaging contrast agent. Peptide cleavage from the nanoprobe by MMP9 was observed in vitro, and distinct pharmacokinetic properties of the contrast agent were observed between tumors with high or low MMP9 expression.
