Intravenously administered multi-walled carbon nanotubes, functionalized with DTPA and radiolabeled with Indium-111, were dynamically tracked in vivo using a microSingle Photon Emission Tomography scanner. Imaging showed that nanotubes enter the systemic blood circulation and within 5 min begin to permeate through the renal glomerular filtration system into the bladder.
