Abstract
The present invention provides microparticles that create permanent tissue markings, such as tattoos, designed in advance for change and/or removal on demand, as well as methods for implanting the microparticles in tissue and changing and/or removing the resulting markings. Colored microparticles are constructed with specific electromagnetic absorption and/or structural properties that facilitate changing and/or removing tissue markings made using the microparticles by applying specific energy (such as electromagnetic radiation from a laser or flash-lamp) to the tissue marking site.
Claims8
A tattoo ink comprising particles, at least one particle comprising a core of at least one pigment or dye and a vehicle that surrounds said core,
- wherein said vehicle or core, or both vehicle and core, comprises a discrete absorption component that alters the corresponding particle when exposed to exogenous energy.
