| Description: |
An iron-centered nanoparticle (left) analyzed at NIST's Center for Neutron Research has a coating of the sugar dextran, whose tendrils prevent groups of the particles from clumping. When tumor cells ingest them (right), the particles still congregate closely enough to share heat when stimulated by a magnetic field, killing the cells. White arrow indicates a red blood cell.
