Abstract

The embedding of radicals at different locations within core@shell silica nanoparticles contributes to enhanced polarization capability and can be self-polarized without adding external radicals. With grafting the radical source homogenously inside of the nanoparticles, a significant ²⁹Si hyperpolarization signal enhancement of 49.4 was obtained.
