Optimizing quantitative in vivo fluorescence imaging with near-infrared quantum dots.

abstract：:Various studies have shown that various cell types can be labeled with iron oxide particles and visualized by magnetic resonance imaging (MRI). However, reported protocols for cell labeling show a large variation in terms of labeling dose and incubation time. It is therefore not clear how different labeling protocols ...
