Enzyme-responsive nanoparticles undergo a morphological transition to network-like assemblies when acted upon by matrix metalloproteinases in a rat model of acute myocardial infarction.
Enzyme-responsive nanoparticles demonstrate targeted accumulation and prolonged retention in heart tissue after myocardial infarction in a rat model.
A method for targeting to and retaining intravenously injected nanoparticles at the site of acute myocardial infarction in a rat model is described. Enzyme-responsive peptide–polymer amphiphiles are assembled as spherical micellar nanoparticles, and undergo a morphological transition from spherical-shaped, discrete materials to network-like assemblies when acted upon by matrix metalloproteinases (MMP-2 and MMP-9), which are up-regulated in heart tissue post-myocardial infarction.

Nguyen et al. (Tue,) conducted a other in acute myocardial infarction. Enzyme-responsive peptide-polymer amphiphiles (nanoparticles) was evaluated on morphological transition and accumulation in heart tissue. Enzyme-responsive nanoparticles undergo a morphological transition to network-like assemblies when acted upon by matrix metalloproteinases in a rat model of acute myocardial infarction.
