New technology, relying on the non-specific absorption of chemicals on the surface of nanoparticles, could enable efficient decontamination of both water and soils. The biodegradable nanoparticles exploit the high surface-to-volume ratio intrinsic to their small diameter, and can be easily removed after use through photoinduced precipitation. This irremediable switching from nano-to macroscale allows limiting the environmental exposure to nanomaterials, possibly presenting a valuable argument toward a broader acceptance of the technology by regulatory agencies and the general public.
