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.
