We developed a novel nanosized and pH-trigged biosensor, which encapsulates high-sensitive 19F MRI contrast agent in gold nanoparticles (AuNPs)-capped mesoporous silica nanoparticles (MSNs) platform,and this biosensor is capable to specifically target to lung cancer cell (A549) for intracellular MRI.
