bS Supporting Information ABSTRACT: Targeting of nanoparticles to ischemic tissues was studied in a murine ischemic hindlimb model. Intravenously injected fluorescent nanoparticles allowed ischemia-targeted imaging of ischemic muscles due to increased permeability of blood vessels in hypoxic tissues. Targeting efficiency correlated with blood perfusion after induction of ischemia and was enhanced in early stages of ischemia (
