Recent advances in matrix metalloproteinases-responsive nanoprobes for cancer diagnosis and therapy
Matrix metalloproteinases (MMPs), a class of zinc-contained endopeptidases, are closely involved in tumor growth, infiltration, metastasis, and angiogenesis.By virtue of the specifically enzymatic hydrolysis, MMPs have been widely used to turn on imaging and/or therapy function of elaborately designed enzyme-responsive nanoprobes, which is expected
