Nanotechnology and Magnetism Partner Against Cancer

Posted on July 22, 2008

Metallic nanoparticles that can locate and attach to specific tumor cells have been developed before. Now a team from Georgia Institute of Technology managed to use magnetite and cobalt nanoparticles to not only attach, but to utilize them as magnets, to pull the nanoparticle along with the cancer cell it is riding on, hence to sort and to sieve malignant from normal cells .From the article abstract:Magnetic cobalt spinel ferrite nanoparticles coated with biocompatible polygalacturonic acid were functionalized with ligands specific for targeting expressed EphA2 receptors on ovarian cancer cel...
