A therapy agent is disclosed that is made up of a functionalized nanomaterial that provides solutions to current problems facing the field of chelation therapies and dialysis of metals, radionuclides, and metabolic wastes. Through the coupling of groups tailored to selectively capture specific toxins and rigid porous backbone structures (e.g., mesoporous silica and mesoporous carbon), suitable materials that are highly effective and fast at capturing toxins (metals, radionuclides, and metabolic wastes) in the presence of competing ions and proteins. These materials may be embodied in a variety of treatment devices which allow for treatment and removal of these target materials through a variety of methodologies including oral, dermal and dialysis pathways.
