Abstract: Proposed are an aqueous two-phase system nanofilter capable of effectively separating particles having different sizes within a short time, and a separation method using same. The aqueous two-phase system nanofilter can separate mixed nanoparticles having a size difference of approximately 10 nm, through the designing of a composition constituting each composition. The separated nanoparticles can be applied across industries such as electronics, photoelectronics and magnetic fields, biomedical, medical and cosmetic fields, energy, catalysts, and structures.
