    • A system and method for removing contaminants from a surface. The system is designed to use particles having means thereon which are capable of selectively binding to a contaminant or contaminants of interest. The particles are applied to the surface whereupon the contaminants bind to the particle. When the particle is removed, the desired contaminants are also removed. Preferably, the present invention utilizes magnetic particles having iron therein. The particles may then be readily removed using magnets. The means for binding the contaminant to the particle preferably comprise a ligand or a charge specifically designed to remove the contaminant of interest. The particles may be included in a carrier to facilitate their application to the surface. The invention is especially useful for the removal of contaminants from skin.
    • 用于从表面去除污染物的系统和方法。 该系统设计为使用能够选择性地结合污染物或感兴趣的污染物的具有其上的装置的颗粒。 颗粒被施加到表面,因此污染物与颗粒结合。 当除去颗粒时,也去除所需的污染物。 优选地,本发明使用其中具有铁的磁性颗粒。 然后可以使用磁体容易地除去颗粒。 用于将污染物与颗粒结合的方法优选包含特异性设计用于去除感兴趣污染物的配体或电荷。 颗粒可以包含在载体中以便于它们施加到表面。 本发明特别可用于从皮肤去除污染物。
