摘要	Matrix metalloproteinase 2, an important modulator of tumor microenvironment, has received significant attention as a biomarker for cancer diagnosis. In this paper, we report a tumor microenvironment-adaptive electrochemical method for sensitive determination of matrix metalloproteinase 2. Metal-organic framework-encapsulated micellar silver nanoparticles, mAgNPs@MOF, are the central element of the method, and are prepared through the coating of micellar silver nanoparticles with zeolitic imidazolate framework-8. Benefiting from inherent pH-responsive ability of MOF coating, mAgNPs@MOF disassemble in the tumor microenvironment at an acidic pH, releasing micellar silver nanoparticles that are consisted of a peptide shell and a silver core. Then, matrix metalloproteinase 2 presented in the tumor microenvironment selectively recognizes and cleaves the peptide shell of micellar silver nanoparticles, which promotes the accumulation of silver cores onto magnetic beads, thereby leading to amplified electrochemical responses. By contrast, in the normal extracellular microenvironment, stable MOF coating prevents matrix metalloproteinase 2 from approaching mAgNPs, and thus inhibits the generation of unexpected interfering signals. Experiment results demonstrate that the method not only displays a wide linear range from 50 fg/mL to 20 ng/mL and a detection limit as low as 20.8 fg/mL for enzymatic assay, but also exhibits high selectivity and anti-interference performance in the extracellular microenvironment of tumor cells. Therefore, the method may pave a valuable way for monitoring enzymatic activity in the tumor microenvironment, and imply a potential use in cancer diagnosis in future. © 2022
