Magnetic nano-'shepherds' organize cells (4/2/2009)

A multidisciplinary team of investigators from Case Western Reserve University, Duke University and University of Massachusetts, Amherst, created an environment where magnetic particles suspended within a specialized liquid solution acted like molecular sheep dogs by nudging free-floating human cells to form chains in response to external magnetic fields. ...> Full Article

Capture of nanomagnetic 'fingerprints' a boost for next-generation information storage media (2/2/2009)

A technique of capturing the magnetic "fingerprints" of magnetic nanostructures -- even when they are buried within the boards and junctions of an electronic device -- has been developed by a team of researchers at University of California, Davis. The technique should serve as a valuable tool in the development of next-generation storage and recording media by contributing to the understanding of how to encode information with nanomagnetic arrays. ...> Full Article

Physicists Discover Gold Can Be Magnetic on the Nanoscale (3/6/2008)

Physicists have found that applying an electrical field on a surface-supported gold nanocluster changes its structure from a three-dimensional one to a planar flat structure. In another paper, they relate their discovery that gold in this size regime can be made magnetic through oxygenation of gold nanowires. They also found that up to a certain length, oxygenated gold nanowires behave as a conducting metal, but beyond that, they become insulators. This marks the first time on the nanoscale that such a metal-to-insulation transition has been found on the nanoscale. Both findings are important predictions that could some day be implemented as control parameters governing the chemical and physical material properties employed in nanotechnology. ...> Full Article
