NIST logo. Click for image: An iron-centered nanoparticle (left) 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.

A research team at Commerce’s National Institute of Standards and Technology (NIST) studying sugar-coated nanoparticles for use as a possible cancer therapy, has uncovered a delicate balancing act that makes the particles more effective than conventional thinking says they should be. In cooperation with The Johns Hopkins University, Dartmouth College, the University of Manitoba and two biopharmaceutical companies, the NIST team has demonstrated that the particles are potent cancer-killers because they interact with one another in ways that smaller nanoparticles do not.
