"Metal particles abraded from tattooing needles travel inside the body"

27-08-2019: Together with colleagues from  the Federal Institute for Risk Assessment (BfR),  the European Synchrotron (ESRF), Physikalisch-Technische Bundesanstalt, Helmut Fischer GmbH and others we carried out a study which showed that, when using titanium-dioxide containing tattoo color, metal particles are abraded from tattoo-needles and travel inside the body. The study is widely covered in all media all over the world.

We are proud to announce the publication of Wang, Hesse et al. "Increased Retention of Gadolinium in the Inflamed Brain After Repeated Administration of Gadopentetate Dimeglumine"

26-04-2019: XPLORAYTION GmbH contributed to a study within the Collaborative Research Center 1340: Highly sensitive synchrotron-based X-ray fluorescence analysis was applied and revealed hot spot regions of Gd in mice brain. This study might help to assess the risk of MRI contrast agent deposition in multiple sclerosis patients.


"Scientists find that nanoparticles from tattoos travel inside the body"



12-09-2017: We are happy to announce that we were part of a crucial study with the Federal Institute for Risk Assessment (BfR) on the transport of tattoo pigments (sub-micron organic pigments, heavy metals and titanium dioxide) from skin to regional lymph nodes by means of micro- and nano-XRF at the ESRF (Grenoble, France). The study was widely covered in all media all over the world. To view the press releases, please click in the logos below:

24-07-2017: "Up to half of all dental implants placed worldwide develop an inflammation at some stage. One of the possible reasons could be the release of particles from the implants into the surrounding tissue. In the first of a two-part experimental sessions, researchers from the Department of Oral and Maxillofacial Surgery (Freiburg University Hospital) and the company XPLORAYTION GmbH are trying to map and characterise the particle distribution in the peri-implant tissue regions.
