Claim:
1. A method of tracking specific cells in vivo, comprising: providing a plurality of fluorescent nanoparticles suitable for targeting specific cells; administering the plurality of fluorescent nanoparticles to a subject, wherein the plurality of fluorescent nanoparticles comprises Gd providing an X-ray source to irradiate the subject, wherein an X-ray image of the subject irradiated by the X-ray source is produced and the plurality of fluorescent nanoparticles are also stimulated by the X-ray source to emit fluorescence; and determining the growth and distribution of the specific cells by the fluorescence emitted by the plurality of fluorescent nanoparticles in the subject irradiated by the X-ray source and observing the growth and distribution of a capillary in vivo by the X-ray image of the subject irradiated by the X-ray source, wherein in the X-ray image of the subject irradiated by the X-ray source, the distribution of the capillary is revealed by the plurality of fluorescent nanoparticles.
