Devices and methods for the precise manipulation of anisotropic particles

A device comprising:

• a chamber defining a volume for containing a suspension comprising an anisotropic particle;
• four co-planar electrodes disposed on an XY plane, wherein the four co-planar electrodes comprise a first pair of opposed and spaced apart electrodes, and a second pair of opposed and spaced apart electrodes orthogonally positioned relative to the first pair electrodes;
• and
• a third pair of opposed and spaced apart upper and lower electrodes, wherein the third pair of electrodes form a space therebetween comprising the four co-planar electrodes and anisotropic particle;
• wherein, in use, the anisotropic particle is electromagnetically coupled to each of the four co-planar electrodes and upper and lower electrodes.
