A real contrast: Multifunctional fluorescent and paramagnetic mesoporous silica nanorods can be used to label both phagocytic and nonphagocytotic cells. The cells can be detected simultaneously by a fluorescence technique and the T1- or T2-weighted modes of magnetic resonance imaging (see picture).
