PERMANENT, REMOVABLE TISSUE MARKINGS

摘要

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.
