+-   SPAM: Janus particles as body submarines? on Friday February 29 2008, @12:49PM Roland Piquepaille

Roland Piquepaille writes "Janus particles, which take their name from a Roman god with two faces, are microscopic 'two-faced' spheres whose halves are physically or chemically different. Now, U.S. researchers have shown that some of these Janus microparticles can move like stealthy submarines when an alternating electrical field is applied to liquid surrounding them. This could lead to new kinds of self-propelling microsensors or means of targeted drug delivery. But read more for additional references and to see how these particles move perpendicular to the applied electric field direction."
