Edith Mathiowitz and her team in Brown University Laboratory at Rhode Island, United States, has made tiny particles coated in polymers. These particles are used to make new permanent ink that will be easily erased by a laser treatment.
Mathiowitz has made microencapsulated beads filled with dyes along with Freedom-2 Holdings Inc., who has funded and holds the license to make and sell their ink (Freedom-2) based on the research.
Micro-encapsulation is a process in which tiny particles or droplets are surrounded by a coating to give small capsules with many useful properties. This technique is usually used as a drug delivery system or for any process that needs controlled release.
The new patented ink can be easily removed via laser. Generally, it takes about 6-7 laser treatments to remove a tattoo using traditional ink, but this ink can be easily removed by a single laser treatment, which breaks the polymer beads, allowing the body to naturally expel the dye that is trapped inside. Moreover, this ink is safer as it is free of heavy metals and other toxins.
The new ink is scheduled for this fall.
