Claim Text:
1. An apparatus comprising: a fixture for holding a substrate; a substrate held within the fixture comprising an array of zero mode waveguides on its top surface, a reservoir for containing a solution in contact with the top surface of the substrate; a solution, in contact with the substrate, comprising magnetic beads having molecules-of-interest attached thereto, the magnetic beads having diameters greater than the smallest cross-sectional dimensions of the zero mode waveguides; and a device for generating a dynamic magnetic field disposed below, adjacent to, or above the substrate capable of generating a magnetic field that (i) pulls the magnetic beads to the top surface of the substrate, and (ii) moves the magnetic beads across the top surface of the substrate, whereby molecules-of-interest are deposited within the zero mode waveguides on the substrate.
