Magnetic titanium dioxide nanoparticles modified with green deep eutectic solvent (DES) composed of choline chloride (ChCl) and xylitol (Xyl) (Fe3O4@TiO2@[ChCl][Xyl]) were synthesized and applied to the solid-phase extraction(MSPE) of chymotrypsin (Chy). The physicochemical properties and morphology...
