nanomag¢ç -D -spio ÃÊ»óÀÚ¼ºÀÔÀÚ Dextran
Biopolymer particles

Magnetic dextran nanoparticles (nanomag¢ç -D -spio)
  • prepared by precipitation of iron oxide in the presence of dextran
  • available with particle diameters of 20 nm, 50 nm and 100 nm
  • functionalized nanomag¢ç -D –spio consist of about 55-85% (w/w) iron oxide in a matrix of dextran (40.000 D) in dependence on the diameter and surface modification
  • differ in the size of the iron oxide domains for different diameters
  • can not be separated with a conventional permanent magnet but in a high gradient magnetic field
  • preferably applied for detection purposes in magnetic resonance imaging or in magneto-immuno assays
  • show good specific power absorption rates for hyperthermia applications for a particle diameter of 100 nm
  • designed with the surface functionalities OH (plain), NH2 and COOH for the covalent binding of proteins, antibodies or other molecules
  • available with covalently bound proteins (avidin, streptavidin, protein A, albumin) or other biomolecules (e.g. biotin)
  • available with various hydrophilic surfaces (PEG 300, PEG-NH2 or PEG-COOH)
  • available with negative surface potentials (e.g. COOH, SO3H)
  • can be provided with covalently bound antibodies on request
