Abstract

Image enhancement: Core-shell MnO@Mn ₃O ₄ urchin-shaped nanoparticles can be synthesized by means of an anisotropic etching process and used as a pH-activatable T ₁ contrast agent for magnetic resonance imaging. The manganese ions released from the MnO phase in the low-pH sites within tumor cells lead to an enhanced T ₁ contrast image for the entire tumor mass.
