Scientists have developed an experimental tattoo ink that changes color under ultraviolet light, using dye-filled polymer nanoparticles to produce multicolored designs. The ink appears differently in visible light, effectively making the artwork vanish when exposed to normal lighting conditions. While the technology could revolutionize body art, researchers emphasize that its safety has not yet been established. The breakthrough raises questions about long-term effects and potential applications in both cosmetic and medical fields.
New tattoo inks use dye-filled polymer nanoparticles to create multicolored designs that appear under UV light and disappear with visible light. Safety remains unproven.
