pH-Triggered Au-fluorescent mesoporous silica nanoparticles for¹⁹F MR/fluorescent multimodal cancer cellular imaging

Abstract

Novel pH-triggered nanoprobe were fabricated for (19)F MRI and fluorescence imaging (MRI-FI) of cancer cells. The biocompatibility, durability, high internalizing efficiency and pore architecture justify the Au-fluorescent mesoporous silica nanoparticles as ideal, highly sensitive and highly specific vectors for (19)F MRI and FI of cancer cells.
