Magnetic particles point the way to nano-compass
Researchers at the University of California - Davis, US, have strung nanoparticles of magnetite onto lithium molybdenum selenide nanowires to make “nano-compasses.” The structures are similar to, although smaller than, those used by certain bacteria to orient themselves with respect to the Earth’s magnetic field. “Our study demonstrates that magnetic fields can be used to control the position and orientation of structures in the submicrometre regime - a finding that could have applications in the assembly and control of nanodevices,” said Frank Osterloh of the University of California - Davis.
