  • Patent number: 7033747
    Abstract: Methods and apparatus for testing a sample for target molecules or chemicals. The apparatus includes a rotatable optical disc having a reaction chamber and having at least two groups of beads or micro-particles, the different group of beads having at least two different densities, sizes, shapes, and/or color, and each bead in a group having different probes attached thereto. A sample is added to the reaction chamber and the disc is rotated. The reaction chamber has a density gradient medium that causes beads of different densities to remain at different radial locations, depending on the density of the beads. The beads are then inspected by directing a beam of electromagnetic radiation onto the disc. The beam may be reflected from or transmitted through the disc. The amount, or presence, or absence of targets is determined by analyzing the signal returned from the beam. Related methods of performing assays and making the disc apparatus are provided.

  • Patent number: 7001608
    Abstract: The invention provides microfabricated devices and methods for directing the growth of a cell process to form an artificial synapse. The devices are called artificial synapse chips. The artificial synapse comprises a nanofabricated aperture (about 50–100 nm in size) that connects the cell process to a chemical or electrical means of neuronal excitation. Such an aperture width mimics the length scales of a natural synapse and thus emphasizes the localized spatial relationship between a neuron and a stimulation source. The invention further provides devices and methods for regenerating a nerve fiber into an electrode. The invention thus provides a regeneration electrode that uses a novel neural interface for stimulation and that uses novel surface methods for directing neuronal growth making possible in vivo connection of the devices to neural circuitry in a retina and other anatomical locations.
