摘要：
A method for preparing chitosan-coated magnetic nanoparticles for protein immobilization includes forming ferrous ferric oxide (Fe3O4) nanoparticles by co-precipitation and coating the nanoparticles with chitosan in the presence of glutaraldehyde. The Fe3O4 nanoparticles can be coated by dispersing ferrous ferric oxide (Fe3O4) nanoparticles into a solution comprising chitosan and acetic acid, adding a surfactant, adding excess 50% glutaraldehyde solution, and washing the nanoparticles with a solvent. The chitosan coated ferric oxide (Fe3O4) nanoparticles can be used to immobilize proteins or other biomolecules.
