Magnetic chitosan microparticles are created by dispersing magnetic iron oxide nanoparticles of about 10 nm in size into chitosan microparticles, with a chitosan content of 4.0%.
The interior of chitosan microparticles has a cross-linked structure, and the particle size distribution is broad, ranging from 40 to 80 μm. On the surface of the magnetic chitosan microparticles, Protein A or Ni-NTA affinity ligands are bound, and they are used in scenarios such as small-scale antibody/protein purification, immunoprecipitation, and pull-down experiments. Other functional groups and unmodified magnetic chitosan microparticles can also be offered as custom products.
