Schematic illustration of platelets as delivery vehicles for NO^· (NO^·@PLT) for magnetic resonance imaging. (A) Schematic illustration depicting the synthesis of NO^·@PLT. (B) NO^·@PLT targeted the tumor and released NO^· micelles. (C) Nano NO^· micelles were enriched in the cerebral glioma. (D) The T1-weighted MRI phantoms were increased after NO^·@PLT treatment
