Abstract
A magnetic particle comprises a polysaccharide matrix and a plurality of magnetic crystals dispersed in the matrix. A method for making magnetic particles comprises combining a basic solution with a metal ion solution and allowing the metal ions to oxidize to form magnetic crystals, and combining the magnetic crystals with a polysaccharide solution to form the magnetic particles.
