Project Description
The surface of the supperparamagnetic Fe3O4 nanoparticles is covalently functionalized with streptavidin, and can be used to bind to biotin-functionalized molecules.
Streptavidin coupled magnetic nanoparticles can be used in bead-based IVD Assay, DNA and RNA purification, protein isolation and analysis
