20140242683 | APPARATUS FOR SELECTIVE EXCITATION OF MICROPARTICLES - Nucleic acid microparticles are sequenced by performing a sequencing reaction on the microparticles using one or more reagents, selectively exciting the microparticles in an excitation pattern, optically imaging the microparticles at a resolution insufficient to resolve individual microparticles, and processing the optical images of the microparticles using information on the excitation pattern to determine the presence or absence of the optical signature, which indicates the sequence information of the nucleic acid. An apparatus for optical excitation of the microparticles comprises an interference pattern generation module that splits a first laser beam into second and third laser beams and generates the excitation pattern for selectively exciting the microparticles by interference between the second and third laser beams. | 08-28-2014 |
20120275005 | Modular Pattern Illumination and Light Beam Multiplexing for Selective Excitation of Microparticles - A modular approach to a pattern illumination system for selective excitation of microparticles is used. A dual-channel pattern module having two single-channel pattern modules are oriented at a non-zero offset angle to each other. In this arrangement, a galvo-scanner based phase-shifting module is shared between the two channels. A set of tilt mirrors are used to direct the beams from the pattern modules onto the target plane. Additional layers of pattern modules can be added to accommodate any desirable number of additional channels. The additional layer(s) may be rotationally off-set from the other layer(s) by an angular amount to simplify the layout of optical components. A remote light source module may be connected to the pattern modules through optical fiber. | 11-01-2012 |
20120231974 | Self-Assembling High Density Ordered Patterned Biomolecule Array and Method for Making and Using the Same - A method for fabricating a universal substrate for attaching biomolecules, including sequencing features and the resulting substrate. A method of direct detection of analytes utilizes a Complementary Metal Oxide Semiconductor (CMOS) sensor with the substrate. | 09-13-2012 |
20110228073 | ILLUMINATION APPARATUS OPTIMIZED FOR SYNTHETIC APERTURE OPTICS IMAGING USING MINIMUM SELECTIVE EXCITATION PATTERNS - A synthetic aperture optics (SAO) imaging method minimizes the number of selective excitation patterns used to illuminate the imaging target, based on the objects' physical characteristics corresponding to spatial frequency content from the illuminated target and/or one or more parameters of the optical imaging system used for SAO. With the minimized number of selective excitation patterns, the time required to perform SAO is reduced dramatically, thereby allowing SAO to be used with DNA sequencing applications that require massive parallelization for cost reduction and high throughput. In addition, an SAO apparatus optimized to perform the SAO method is provided. The SAO apparatus includes a plurality of interference pattern generation modules that can be arranged in a half-ring shape. | 09-22-2011 |
