13. A method for detecting fluorescence emitted by intestinal cells in vivo, comprising the steps of:

  • a. introducing an autonomous solid support into the lumen of the intestine;

    b. illuminating cells in the intestine wall from a light source mounted to the solid support with a wavelength that excites a particular fluorescent signal;

    c. detecting at a detector mounted to the solid support whether illuminated cells illuminated during step b emit the particular fluorescent signal; and

    d. if the particular fluorescent signal is detected from the illuminated cells, then determining at least one of an intensity and a position in the intestine of the detected fluorescent signal.
