Scientists at Binghamton University (State University of New York) have analyzed nearly 100 different tattoo inks and found that the manufacturers' ingredient labels (when used) are often inaccurate and that many inks contain small particles at the nanoscale that could be harmful to human cells. They presented their findings at this week's meeting of the American Chemical Society (ACS) in Chicago.
According to principal investigator John Swierk, a chemist at Binghamton, the project initially started when his group became interested in tattoos as tools for medical diagnostics. This shifted to an interest in tattoo laser removal, specifically how laser light causes tattoos to fade. "We realized we didn't understand a lot about the interaction between light and tattoos," Swierk said during a press briefing at the ACS meeting. "My group studies how light can drive chemical reactions, so it was a natural fit."
