Provided is a method of moving a charged particle from a first position at which it is retained by a first electrode to a second position at which it is retained by a second electrode, the method comprising: applying a potential to the second electrode to attract the particle; and applying a potential to a guide electrode offset from the particle at the first position, wherein the applied potential is effective to reduce the attraction of the particle to the first position sufficiently to allow the potential applied at the second electrode to be effective to move the particle from the first position to the second position.
A method of moving a charged particle from a first position at which it is retained by a first electrode to a second position at which it is retained by a second electrode, the method comprising:
A transporter chuck for attracting particles to first or second bead retaining zones (BRZ) on a bead contact surface (BCS), and for allowing assisted transfer of at least one of the particles from the first bead retaining zone to the second bead retaining zone, the transporter chuck comprising:
A method for transporting beads using a transporter chuck for attracting particles to first or second bead retaining zones (BRZ) on a bead contact surface (BCS), and for allowing assisted transfer of at least one of the particles from the first bead retaining zone to the second bead retaining zone, which transporter chuck comprises:
