Streptavidin is covalently conjugated to the surface of iron oxide nanoparticles with amphiphilic polymer coating. 

NP-Strep: Streptavidin Conjugated Iron Oxide Nanoparticle

    • Amphiphilic polymer coating
    • Covalently conjugated streptavidin for highly affinitive biotin binding
    • High stability in water, buffers, cell culture media, and biological samples
    • Minimal non-specific interactions will biomolecules and cells
    • Selections of amine (-NH2), carboxyl (-COOH) or no surface active group
