Article Correctness Is Author's Responsibility: Controlled dynamics of colloidal rods

(Universität Bayreuth) Colloidal particles have become increasingly important for research as vehicles of biochemical agents. In future, it will be possible to study their behaviour much more efficiently than before by placing them on a magnetised chip. A research team from the University of Bayreuth has discovered that colloidal rods can be moved on a chip quickly, precisely, and in different directions. A pre-programmed magnetic field even enables these controlled movements to occur simultaneously.
