ABSTRACT:
A system and method for removing contaminants from a surface. The system is designed to use very small particles having means thereon which are capable of selectively binding to a contaminant or contaminants of interest. The particles may contain a dye to render the particles visible in order for a user to observe the application and removal of the particles. The particles also have magnetic properties which may be provided by a high iron content. A carrier can be used to apply the particles to a surface whereupon the targeted contaminants bind to the particles. The particles may then be readily removed from the surface using magnets. When the particle is removed, the targeted contaminants are also removed. The invention is especially useful for the removal of contaminants from skin.
