How to find out just what is in tattoo ink

Metallic contaminants in tattoo ink can be identified using Postnova AF2000 FFF system

The growing popularity of tattoos, especially among young adults, raises concerns about the composition of tattoo inks and any potential long-term health effects they present. The European Commission Joint Research Centre recently noted that about 12 percent of Europeans have…

AFM probes can be 3D printed

Examples of specialised probes created by the technique, including (lower left) one modelled on the Matterhorn, a mountain in Switzerland

A NOVEL application of 3D printing techniques at nanometre scales could make the creation of custom probes for atomic force microscopy (AFM) both quicker and cheaper, according to researchers at Karlsruhe Institute of Technology. They have developed a technique based…
