Dextran CLIO Magnetic Nanoparticles - Streptavidin

General Information
Streptavidin functionalized Dextran coated crosslinked iron oxide nanoparticles (CLIO-STRP) have 1-3 superparamagnetic Fe3O4 iron oxide cores (8-10 nm in diameter) imbedded within the matrix of dextran strands of 40 or 70 kDa in size. Dextran strands are crosslinked to prevent their disassociation, ensuring long-term biological stability. Streptavidin is covalently conjugated to the nanoparticle.
