Figure 1From: Investigation of magnetically controlled water intake behavior of Iron Oxide Impregnated Superparamagnetic Casein Nanoparticles (IOICNPs) Schematic formation of IOICNPs (Step-I) Formation of casein nanoparticles by crosslinking of casein macromolecules by reaction with glutaraldehyde. (Step-II) Impregnation of iron ions within the casein nanoparticls network by swelling in iron salts solution. (Step-III) In situ precipitation of iron oxide within the casein nanoparticles matrix to yield IOICNPs.Back to article page
