A recently published study by scientists from Germany and the ESRF, the European Synchrotron, Grenoble (France), have found that elements from tattoo ink circulate inside the body’s immune system and stain lymph nodes.
Scientists already knew that pigments from tattoo ink traveled to the lymph nodes by observing the visual evidence of the stained nodes, however, this study marks the first time researchers have found analytical evidence of the transport of these micro- and nano-particles through the immune system.
