At their core, MMP-cleavable peptides function as molecular triggers. When incorporated into larger structures like hydrogels or nanocarriers, their degradation by specific MMPs can initiate a desired response. For instance, a MMP-cleavable peptide can act as a stimulus-sensitive linker, releasing a therapeutic agent only when it encounters the elevated levels of MMPs often found in disease microenvironments, such as tumors. This targeted activation minimizes off-target effects and enhances therapeutic efficacy.
