This tattoo patch is painless and works just like any other microneedle-based patches. vaccines The mold pattern may include numbers, letters or symbols. Every microneedle slot can be thought of as a small pixel in an image.
Researchers create the mold and fill it with tattoo ink. They attach a patch at the back of the body to help hold the needles against the skin. After a short time, the microneedles will dissolve ink and be released into the skin. This process is painless. There’s no risk of infection or bleeding. It may last up to a year, and the result could be permanent. researchers report In the journal iScience.
You can use tattoos in medical settings where they are useful, like disguising scars or guiding repeat cancer. radiation treatments, or painting on new nipples during breast reconstructive surgery.
“The goal isn’t to replace all tattoos, which are often works of beauty created by tattoo artists,” Prausnitz said. “Our goal is to create new opportunities for patients, pets, and people who want a painless tattoo that can be easily administered.”
