Carbon nanotubes allow capture of krypton, barium and lead for multichannel biological X-ray fluorescence imaging
Abstract
Biological applications of x-ray fluorescence (XRF) imaging are currently limited to mapping naturally occurring elements in tissues. Here, the authors encapsulate toxic elements in functionalized single walled nanotubes, and use them as non-toxic XRF contrast agents for imaging specific cellular organelles.
