20090121133 | IDENTIFICATION OF NUCLEIC ACIDS USING INELASTIC/ELASTIC ELECTRON TUNNELING SPECTROSCOPY - The present invention relates to a method for identifying a nucleotide in a nucleic acid including stretching a nucleic acid to an extended conformation, subjecting a nucleotide of the stretched nucleic acid to electron tunneling spectroscopy, and obtaining a current-voltage curve or a current derivative-voltage curve as a result of the stretching to provide a resonance signature of the nucleotide in the nucleic acid. The present invention also relates to a method for sequencing a nucleic acid. The method includes stretching a nucleic acid to an extended conformation, the nucleic acid including a plurality of nucleotides, subjecting each nucleotide of the stretched nucleic acid to electron tunneling spectroscopy, and obtaining a current-voltage curve or a current derivative-voltage curve as a result of said subjecting to provide a resonance signature of each nucleotide in the stretched nucleic acid. | 05-14-2009 |
20090213459 | CONTACT LENS FOR THREE DIMENSIONAL VISUALIZATION - A contact lens set for stereoscopic visualization includes a left contact lens comprising a first lens substrate incorporating a first polarizer, and a right contact lens comprising a lens substrate incorporating a second polarizer. The first polarizer comprises a first plurality of parallel lines having sub-wavelength pitch and oriented in a first direction. The second polarizer comprises a second plurality of parallel lines having sub-wavelength pitch and oriented in a second direction. The left contact lens and the right contact lens each comprises a rotational stabilization means, such that, during use, the first direction is adapted to orient in an approximately orthogonal direction to the second direction. In another embodiment, a contact lens set for stereoscopic visualization includes a left contact lens and a right contact lens, each coded with different colors. | 08-27-2009 |
20090230174 | SELF-ASSEMBLY OF ELEMENTS USING MICROFLUIDIC TRAPS - A self-assembly process is disclosed for integrating free standing microcomponents onto a template having a plurality of binding sites, an interconnect network, and trapping structures disposed downstream of the binding sites. The self-assembly is accomplished by flowing a fluid medium containing the microcomponents over the template such that some of the microcomponents are trapped at binding sites. The template may be simultaneously (or subsequently) heated to melt a binder such as a solder spot at each of the binding sites, and then cooled to connect the trapped microcomponents to the interconnect network. In one embodiment, removable blocking elements are disposed upstream of some of the binding sites, for example formed from photoresist. After assembling a first set of microcomponents, the blocking elements are removed, and a second set of microcomponents in a fluid medium are flowed over the template for assembly into the newly unblocked binding sites. | 09-17-2009 |
20090236310 | Adjustable solubility in sacrificial layers for microfabrication - The present invention provides fabrication methods using sacrificial materials comprising polymers. In some embodiments, the polymer may be treated to alter its solubility with respect to at least one solvent (e.g., aqueous solution) used in the fabrication process. The preparation of the sacrificial materials is rapid and simple, and dissolution of the sacrificial material can be carried out in mild environments. Sacrificial materials of the present invention may be useful for surface micromachining, bulk micromachining, and other microfabrication processes in which a sacrificial layer is employed for producing a selected and corresponding physical structure. | 09-24-2009 |
20100001926 | CONTACT LENS WITH INTEGRATED LIGHT-EMITTING COMPONENT - A light-emitting contact lens and a method and system for tracking a user's eye position using the light-emitting contact lens are disclosed. The eye position tracking can be used, for example, to allow the user to interact with a display device such that the position of the user's eye determines the image generated by the display device. Thus, as the user's eye moves, the image on the display device will be altered to represent the new position (e.g., viewing angle) of the user with regard to the display device. | 01-07-2010 |
20100096640 | SELF-ASSEMBLED HETEROGENEOUS INTEGRATED OPTICAL ANALYSIS SYSTEM - Optical analysis system fluidically self-assembled using shape-coded freestanding optoelectronic components and a template having shape-coded recessed binding sites connected by an embedded interconnect network. Also includes methods of manufacture and use for optical analyses. | 04-22-2010 |

20100186226 | FLUIDIC SELF-ASSEMBLY FOR SYSTEM INTEGRATION - A method for self-assembly is disclosed that accomplishes the assembly process in one step, obviating or mitigating the need for post-processing of an assembled macro-electronic device. Microcomponents are fabricated having a particular shape, and a template with embedded interconnects is fabricated having recessed binding sites that are sized to receive particular microcomponent types. The binding sites include a low melting point alloy for electrically connecting received microcomponents to the interconnect network. The template is placed in a liquid, and the microcomponents are introduced to the liquid such that the microcomponents flow or slide along the template propelled by gravity and/or fluid-dynamic forces and some of them are received into the binding sites, and retained by capillary forces. The liquid is heated before or after introduction of the microcomponents to melt the alloy. The fluid and/or template are then cooled to harden the alloy, binding the microcomponents. | 07-29-2010 |
20110012217 | FREE-STANDING TWO-SIDED DEVICE FABRICATION - Devices having features deposited on two sides of a device substrate and methods for making the same. The devices are useful, for example, as the components in a macroelectronic system. In a preferred embodiment, the devices are photosensors having a plurality of electrodes patterned on a first side of the device and an electromagnetic interference filter patterned on a second side of the device. The method facilitates the fabrication of two-sided devices through the use of an immobilizing layer deposited on top of devices patterned on a first side of a device substrate; flipping the device substrate; processing the second side of the device substrate to produce patterned features on the second side of the device substrate; and releasing the devices having patterned elements on two sides of each device. | 01-20-2011 |
