Micro-Chip Technology Resurrects Tattoo Identification + Medical Surveillance


“The tattoo-esque technology, described today in the journal Science Translational Medicine, is still in the early stages of development, and hasn’t yet been tested in humans. But the team’s experiments in rats suggest that these medical marks are both safe and long-lasting, and can be administered alongside vaccines without compromising efficacy.”

Wu goes on to report that “though somewhat comparable to tattoos, the marks are delivered by a microneedle patch—a four-by-four grid of tiny, 1.5-millimeter-long spikes made up of nanoparticles that are undetectable in visible light, glowing only when viewed in infrared.  Within two minutes, the nanoparticles diffuse into a layer of the skin”.
