Near-infrared fluorescent silica-porphyrin hybrid nanotubes (HNTs) were successfully synthesized by π-π stacking, electrostatic interaction and a sol-gel reaction. The HNTs-labeled macrophages were detected in vivo, and the minimum detectable number of cells was 200. Furthermore, the biodistribution of HNTs-labeled macrophages was tracked by fluorescence imaging.
