    The effect of a shaped electrode geometry array on the dielectrophoretic transport and characterisation of nanometre-sized particles, including possible biological material, was investigated. Polarisable particles placed within a non-uniform electric field are subject to dielectrophoretic force acting upon them. Use was made of an electrode array to investigate the transport and separation of nanometre-sized particles. Electrode arrays having electrode and gap dimensions of micrometre size were utilised to produce an electric field of sufficient magnitude for dielectrophoresis of the submicrometer sized particles to occur. An ac electric signal was applied to electrodes within the electrode array; the electric field thus created was switched sequentially along the electrode array at a frequency to track the particles' movement. Electrode geometries were investigated to maximise the efficiency of particle transport.
